AutoCAD Inventor :: Frame Generator Instability Of Node Error
Aug 28, 2013I keep getting Instability of node errors in my Frame Generator. Specifically type 3 at node 62 in direction RY. I am new to FG results seem reasonable just can't get past this error. I tried deleting the member and inserting a new one in its place. The error then goes to another node?
The application is a steel box frame being lifted by a crane, FWIW. when you create special parts for FG and post them from Iparts, where do they go? I need to go back in and alter some properties.

AutoCAD Inventor :: Nodes In Frame Analysis
May 3, 2013I 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.

Jan 27, 2013I 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.

AutoCAD Inventor :: Lost Frame Analysis Menu Bar
Sep 23, 2010When 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.
AutoCAD Inventor :: Frame Analysis UDL And Point Loads
Oct 10, 2012I 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.
AutoCAD Inventor :: Adding Force In Frame Analysis?
May 2, 2013I 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.

Jan 23, 2012I 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.
AutoCAD Inventor :: Structural Shape Authoring And Frame Analysis
Dec 30, 2010I 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.

Mar 27, 2012I have made a VB.Net Add-In for Inventor 2011, in a few functions it opens one or more files or sets a reference to already opened files. The release of the resource to this documents seems to be the problem.
In PDM (Productstream Pro) we want to change document states and there for the documents have to be closed in Inventor. When using some Add-In functions prior to the state change in PDM, we get a message from PDM that Inventor still has the files open but inventor does not show any open files (of course we can not see files that were opened in the background).
Only manual operation to solve this is to close inventor or open the drawing and the part used on the drawing and close them top down (drawing first, then part).
I'm stuck with open files that don't seem to be open.I think this is because the add-in sets a reference to the part used on the drawing and then changes something in the drawing.How do I release the resources correctly?
AutoCAD Inventor :: 2011 Add-In - How To Release Document Object Correctly
Jan 26, 2012I've created a Inventor 2011 Add-In using VB.Net with VS2008.
This add-in does all kinds of things, but it will not release some documents.
Well I don't know that for shure but it looks like that.
We use Productstream Pro and when changing state of a document it says the document is in use while there are no documents visibly open in Inventor. This only occures when I use my add-in.
Exact steps: Load drawing document from PSPPerform action with add-in which gets a custom iProperty from the Part file used on the Drawing and fills the display name of the Drawing with itSave the drawingClose the drawingIn PSP try to change state of the part file used on the drawingGet message from PSP stating the part is in use
In my code I've tried some things to prevent this behavior but non of them work.
I've tried:
Setting unused objects to "= Nothing"Releasing objects using "Marshal.ReleaseComObject(obj)"Calling "m_inventorApplication.CloseAllUnreferencedDocs()" and "System.GC.Collect()" on the "m_appEvents_OnTerminateDocument" event.

Jul 26, 2012I come across this problem from time to time and generally either just ignore it, if the detail is destined for in house manufacture, or alter it in autocad if it's destined for exterior suppliers.
Our guard frames are manufactured from extruded aluminum section (made by a company called palletti) I have when needed created a new frame generator frame member for each new x-section that we wish to use. I then draw a 2d sketch for the base frame skeleton and then a 3d sketch for all the frame work above. This I then use in an assembly to create the framework. This framework assembly then goes into a second assembly where the framework is then adorned with all the accoutrements that make up a guard frame that we can then order as an assembled frame, panels feet, hinges et al.
When placing the views for the detailing of the second assembly sometimes the view will show the wrong length for one or some of the frame members.
;note how the left and right views are different and how some of the frame members are elongated on the lh view.
I'm guessing its because of the home grown frame members but all seems to work well other wise and this only happens infrequently.
