I have tried the Frame Analysis for the first time and quit from this option as requested.
BUT now the subassemly consisting frame and all its parts are grey even after restarting Inventor.
Here is some bug. [URL] ....
I have created a report from a frame analysis of an arrangement of I-Beam steelwork. I need to check that I have placed the nodes in the right order and this is reflected in the results of the report. I have the parent and child nodes connected at the ends of the beams as shown on the attached screen shot. I'm interested to know if the order in which I have selected the nods makes any difference to the results. There a 3 node connection points at each corner section.
View 3 Replies View RelatedI am trying to run a simulation on a 4 layer part that has two base layers of I-beams, a frame I made in the frame generator (below) and a solid sheet on top. I am having some issues with the FEA side and was curios to see if the frame analysis tool would yield the same results as the stress analysis simulation. For the frame generator I saw 4 times the amount of deflection despite using (what I believe) are similar loading and constraints, however now I am unsure if I can trust to run an FEA simulation with a frame generated component. The frame is made up of 2 inch steel box beam with a 0.25 inch wall thickness. For the frame analysis package, I have applied a pressure that equates to a 70 kN load across four different sections of the frame. Supports have been placed under all four corners, with 1 being fixed and the other 3 free to move. For the FEA simulation, I applied a similar pressure by creating 2 inch wide plates and applying the same pressure at the same four points. There are also 2 inch square pads under the four corners of the frame with one edge of one pad being fixed and the bottom of the pads having a frictionless constraint. There are separation contacts between both the pressure plates on top of the frame and the frame as well as between the pads and the frame.
with the frame generator is that all the segments of the frame are bonded together (under contacts) which makes sense since they are welded together. However when I put a sheet on top of the frame, there are 3 contact points created between each beam on the frame and the sheet (one on the face of the frame that is in contact with the sheet and the other two on the rounds of the frame and the sheet, even though the rounds are not actually in contact with the sheet). Either way, I am seeing deflections of less than 0.1 mm when a 70 kN load is applied which I know is not right and just want to know if using a frame generated component is not possible with an FEA simulation.
I've attached file. This is trestle and SWL(safety work load) is 2T. How can understandable that this load is going to be withstand by trestle.

Nothing special had happened prior to this problem. It happened with some absolutely irregular and not systematic affection as like a fallen and broken ink bottle makes something completely colored and some other stuff just partially and some not.
I mean some parts properties are completely grey and some have just several grey properties while some other are not affected (see video link)
It is a permanent bug and seems it belongs to the part itself since the reloading Inventor and windows and Task Scheduler attempts to fix it - all gray colors stay exactly where they were before and in same irregularity. Opening the affected parts in other project gave the same result as in original one.

Having an assembly, modeled in the frame generator, then with some additional parts (ribs, plates, etc) added to the assembly as parts and constrained with assembly constraints.. which is the best way to do a frame analysis with the frame analysis enviroment for considering the all structure (frame generators parts + the additional enforcing parts) ?
The assembly look like for example, to this (modeled in autocad).
explain the circumstances where 'Release' is applied to a beam (node?) when using the Frame Analysis tool.
View 1 Replies View RelatedWhen I go to Environments>Frame Analysis, I used to get a menu for Constraints, Loads and other settings (similar to the Stress Analyisis menu). I don't get that now. I can right-click on an existing simulation and add constraints and loads, but I would really like to get the menu back.
I can go to tools>Customize, Toolbars tab and Frame Analysis Panel is there. I can click Show and it will show the panel but it stays up all the time. Not what I want.
I have tried resetting the menu, repair installing Inventor and Reinstalling Inventor, but still not joy. How do I get this back to the original setting so that it comes up when I select Frame Analysis?
This is in 2011.
I understand that in a normal part to apply a load to a face is to make it a UDL (uniformly distributed load) by default. To apply a point load, I was told to create a small sketch and use it to split a face to create, in effect, a small face on which to apply a load, effectively making it a point load.
Now in the frame analysis environment, there is clearly an option for 'force' and one for 'continuous force' which the description clearly describes as a uniformly distributed load. However, when I run the simulation (on a 2m long 100mm x 50mm x 4mm Rectangular hollow beam) with a normal load in the middle of the beam (1m offset); the maximum moment comes out at 500000 Nmm or 500 Nm. By my reckoning the moment should be 1000 Nm as the basic formula for a moment from a point load is M = F*D (Moment = Force * Distance). However, to get 500 Nm, it looks like Inventor is using M = (F*x^2)/2 where x is the midspan of the beam (in this case 1m). .is a normal load in frame analysis the same as a UDL? If so..how to I make it a point load?
There are also some errors stating instability of type 2 at various nodes, I've used both Pinned and Floating constraints at either end of the beam.
I have a question regarding adding a force constraint in the Inventor frame analysis environment. When I add the fixed constraint to the beam the orientation indicator is incorrect - the square indicator being not parallel to the base of the beam. I would like to know why this is and as I am relatively new to frame analysis if I am doing something wrong. I have attached a screen shot of the placement of the constraint on the beam.

Does Frame Analysis uses the finite element method?
If it does, how to view/edit the mesh?
I am trying to run a Frame analysis on a beam structure. I wanted a specific yield stress for the components that make up the beam. So I created a new material and changed the yield stress and change my beam components to that new material. However when I run the simulation the yield stress is not what I made it. Is this allowed?
View 6 Replies View RelatedI am busy constructing my own Structural Shapes Library in Inventor 1012.During the Authoring and Publishing step I mapped Cross Section Properties (Ixx, Iyy, Torsional Section Modulus, Torsional Rigidity Modulus etc) to set parameters in my iPart table.
I have noticed that once this part is then used in Frame Generator to create a simple beam and then analyzed with the Frame Analysis tool, the analysis tool uses the geometry of the part to calculate these properties.
Is there a way that I can force Inventor to use the properties in the iPart Tables? I am worried that any errors in creating the cross section geometry will be carried into the Cross Section Properties calculated by Inventor.
I created a structural shape profile for use in a project. It is square tube with radiused corners, very similar to "ANSI/AISC (Rolled Steel) Structural Tubing Square" in the content center, but mine is 1 inch square with 0.065 inch walls.
I've made a chassis out of my custom tubing. When I run a frame analysis on it, I get an error/warning stating that the torsional section modulus is zero, because I didn't fill in the value when I generated the frame. How do I calculate that value?
I've attached the tube that I used to make the structural shape.

View 9 Replies View RelatedDoes frame generator update placed components when the profile of a custom structural shape family changes?
Workflow:
1. Create custom family in Frame Generator library.
2. Place instances in a frame generated assembly.
3. Make a profile change to the base shape and update the library using "Replace Family Template"
4. Open assembly with placed components and select Design > Frame > Refresh.
The profiles of already placed components do not update. Existing parts are unchanged even though any new parts placed from the family receive the new profile.
Under our previous workflow using derived parts, we created sketch files and saved them in a profile folder. Then all lineal lengths derived their base sketch from those profile .ipt files. When the sketch changed in the base .ipt, all the files derived from it updated. I am trying to replicate / improve this workflow using Frame Generator, but it doesn't seem to work.
Am I doing something incorrectly? Or does Frame Generator not support automatically updating existing frames when the profile of the family template changes?
Is there any way to group assembly components?I'm aiming at a live mass calculation for different level of details/design views.In this case I'v got an assembly with about a ton of stainless steel spread out on different subassemblies.
I have made representations showing only the welded stainless steel and I would like the weight of these to appear in the partlist. Not the weight of the complete subassemblies.
My design consists of two steel rails that are welded together on top of a guardrail system. To allow the weld to be added between the steel rails I have converted my assembly file to a weldment.
My question is now I have this converted assembly with it's weld in the design can this still be used to perform stress analysis on ? I am not sure the need for assembly to be converted to allow a weld to be added.
When creating a break out view on a top level assembly that includes frame generator components, the break out function does not break these parts out. I know it is working because the non-frame generator parts are disappearing and being broken out as you would expect but the frame generated parts seem to be immune to the command. is this a common fault or something wrong with my particular model?

change template file for frame-generated components?
I am working on a large plant piping project and while I've seen this behavior before I've never seen it this bad.
Attached is a screen shot of a small portion of the assembly drawing in which you can see a good example of what I'm dealing with.
At the top you can see a weld neck flange that appears to be attached to air where there should be an elbow. In the middle you can see that on one side of the elbow there is missing geometry.
At the bottom is another flange that attached to air where there should be an elbow. This drawing is littered with these errors and as such is unsuitable for even a reference document.
I have turned visibility of these components off and on without resolution. I have turned on tangent and interference edges without resolution.
I have translated a copy to ACAD to see if it's simply graphical but the ACAD file shows the same errors. I have checked parallel and perpendicularity and all is well.

In past I replaced components in Assemblies with this sub:
Sub testReplacePartInAss()
Call ReplacePartInAss("W:INVENTORTPart1.ipt", "W:INVENTORTPart2.ipt")
End Sub
[Code] .....
But if the assembly is a weldment assembly the line
If oOcc.ReferencedDocumentDescriptor.FullDocumentName = sInAssFilename Then
creates an error '91' that the object is not set.
What has to be changed in this code so that it will work with 'normal' assemblies AND weldment Assemblies too.

I can Open and save each file but that will take me for ever.
Can it be done with iLogic?
I'm running Inventor 2008 SP2. Each time I open the assembly 2 subassemblies always explode. You can see the red and blue subs in the attached picture. I thought this was supposed to be fixed by now. Actually I thought this was supposed to be fixed in R11 a long time ago. When I grab and drag either component, everything snaps back to where it's supposed to be.
If this isn't fixed (along with a laundry list of stuff that's been broken since R10) you will be losing customers. This and all the other bugs have cost me countless hours in lost productivity.
In Inventor 2012 I know that it is possible to arrange assembly components in a circular or rectangular pattern. But is there a way to arrange these components in an oval pattern?
View 5 Replies View RelatedI need to modify all the ipt in an assembly, but I don't kow how many ipt I have, and I don't know the name. Can I have with iLogic the list of all the ipt used in the assembly ? For example, to modify the Part Number in all the components.
The code should be like this :
For All component in Assembly
...
...
Next component
Here is the history. I originally created a part with multiple solid bodies.
After creating it I was told we needed to make it an assembly. So what I did instead of recreating each component I called up the original multi-bodied part and did save as copies.
Then deleted the portions of the model I didn't need with only the part needed left.
Then I took all of those parts and assembled them together to form an assembly.
Now, here inlies the problem. When I go to make a drawin gof this assembly all of the balloons are coming up with the same item number as it was when it was a multi-bodied part.
It is clearly an assembly based on the model tree and the file extension.
I have a machine assembly with old part naming. Now we have a new part naming system. So i am supposed to rename all existing parts, assemblies to new naming system.
E.g. : A machine assembly with old names (lets say part1, part2..... part1000). It has to be renamed to new names (say item1, item2.....item1000).
"part1" should be renamed as "item1" and so on.
Design assistant is not a good option because its a lot of manual work, its same issue with using Vault.
Currently I have some code which loops through all sub components of an assembly and sub assemblies. However I only need sub components inside the top level assembly and not any sub-assemblies. Is there an easy way to acomplish this?
This code will list all sub components inside an assembly when a drawing is open.
Dim oDocument As Document Set oDocument = ThisApplication.ActiveDocument Dim oRefDocs As DocumentsEnumerator Set oRefDocs = oDocument.AllReferencedDocuments
Dim oRefDoc As Document
For Each oRefDoc In oRefDocs debug.print oRefDoc.FullDocumentName Next
It seems to me that the basic exclude component no longer works when deriving assemblies. If I cycle through components it is not possible to get the Grey circle with the backslash through it?

I'm using I-logic to suppress components in an assembly. I've attached a screenshot with 3 suppressed components.
In the browser the parts are suppressed but in the BOM (items 6,7,9) they are not. Is there a piece of code for this?
