using inventor for FEA analysis in inventor on an imported SolidWorks file. But I am now having trouble creating a good mesh on an assembly. The largest part of the assembly gets an error "mesh failed: body failure:filename". I have attached a snip of the aftermath of the "mesh view".
View 3 RepliesEvery once and a while a get an error while I am trying to generate a mesh for a part. The error says: Warning:1 No additional information is available. Internal error in the mesher.Sometimes I can go back to the part and change a dimension exit the sketch and then change the dimension back to the original value and then I can get the mesh to work. Today I can't get the mesh to work. How I can do eliminate this error?
View 9 Replies View RelatedI have imported an .igs and would like to use it on my assembly.
Step that I created.
1. DL an igs files, then open it in Inventor 2012 Product Suite.
2. Save as .ipt,
3. Create a new .ipt and then DERIVED the save .ipt, change scale to 25.4
4. Save the part
5. Open .idw and place the part you just save.
Result: Notice that nothing is visible. WHY?
I'm currently creating a procedure to manage a standard part library.
For that, I'm trying to import downloaded STEP files from suppliers online libraries, and some of these STEP files contain assemblies.
I can open them as wanted in Inventor (1 .IAM and .IPT files), problem is I can't edit .IPT names. I can only rename them in Windows, but I would like to rename in Inventor before saving for the first time.
I would like to have something like that, with "Assembly" the assembly name:
Assembly.IAM
Assembly_1.IPT
Assembly_2.IPT
Assembly_3.IPT
...
How can I do that without renaming in Windows?
I attached the STEP file I'm using, downloaded form McMaster.
A lot of times our customers will send sheet metal parts for us to manufactur. unfortunately they do not have inventor and/or do not, or won't, send the flat layout. It is possible for me to convert these 3d files into Inventor sheet metal pieces and lay them out so i don't have to re-draw? What are the steps to do so?

My issue however is a Client has given me sone .stp's and Iges files to work with.They open fine as a .iam The issue is saving. I have the project folder setup, go to save.
I Get the "do you want to save changes to "XXXXXXXX.iam" and all its dependants.I select "yes to all".I get the "Yes" under the "Save" Column for all listed .ipt's...I hit OK.......Autodesk attempts to save.
...Then I get the dialogue box up with ! icons "The system cannot find the path specified" - The database in C:Users.........xxxx.ipt could not be saved
i just started using inventor 2013.
it seems that there's a setting so that when it imports steps it assigns weld bead colours to all the surfaces of the imported model. is there a way to change this behaviour so that it imports with solid colour surfaces instead?

I am working on modeling a pond riser. I had one model with a series of small round perforations in the riser and I needed to look at a version that used larger, square cut-outs in the riser. So, I performed a "save-as" and adjusted my orifices to match my new model requirements. When I attempted to run the model, I received the following error: "ERROR 537 : Unable to perform multiple storm analysis, no storm was selected.".
I have encountered this one time before and was able to go back to the first model and start over. However, now, even when I run the first model (small round perfs), I receive the same error.
I have a storm event assigned for both models but the program does not seem to recognize this any longer.
I am trying to share an assembly with some design accelerators and content center files and it seems to be not possible. I changed the directory of the application>file>content center to the same location on both PC but it is still not working.
View 2 Replies View RelatedThe goal of this project is to take a base part file, save new copies as needed, then modify the copies. They're rings for storage tanks that share the same tank diameter but differ in height and thickness. I have a SaveAsCopy rule in my template ring part that I run externally from my main assembly after passing down the new file names to the part rule. Since I'm testing a lot, I'm always deleting the parts from the assembly, then clearing out the new copies from my folder and running the rule again. Eventually after 1-5 times inventor starts giving me an error.
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
The More Info Tab:
System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG)) at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData) at Inventor.Document.SaveAs(String FileName, Boolean SaveCopyAs) at LmiRuleScript.Main() at Autodesk.iLogic.Exec.AppDomExec.ExecRuleInAssembly(Assembly assem) at iLogic.RuleEvalContainer.ExecRuleEval(String execRule)
The two other posts on here that deal with that error say it involves enumerating an array that is being changed and looking for an entry that is gone. I have a feeling it has to do with a left over variable (but this is all in iLogic rules so they get cleared at the end of the rule?), temporary files or remnant file references. It works again if I close the assembly and open it back up. Inventor 2013 SP 1.1
I have succesfully installed Autodesk Inventor 2011 (Student License) on my Windows 7 (64-bit) operating system without any errors. I can open Inventor 2011, but when I try to open a new or existing file, Inventor suddenly closes and the 'Autodesk Inventor Error Report'-window opens, giving the following error:
Error: Unhandled Exception
When I go to my project folders and try to open any inventor file, the following message appears:
"Inventor.exe needs to register with he operating system and the following programs (Explorer) are running and may
prevent registration from succesfully completing. Autodesk recommends terminating the offending processes to ensure proper registration. Terminate these processes before continuing with the registration?"
If i cick 'Yes', the problem remains.
I've tried reinstalling, following the instructions carefully (installed as administrator), without success. I installed both service packs. I keep having the same problems, while in the past, it has been working perfectly, but I lost it because of hardware problems, which are now resolved.

I`m trying to determine will Inventor satisfy the needs that I`m having regarding simulation options. So I started with some elementary stuff.
If it is possible in stress analysis to manually select which degrees of freedom body has.
"Fixed constraint" block all 6 DOF and I would like to block only transitional DOF so that I keep rotational degrees of freedom?
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 1 Replies View RelatedI am trying to simulate the following:
I have an 8" OD/5.523" ID steel tube. A 5.5" OD/4.957"ID tube is placed inside. The 8" and 5.5" tubes are placed over a 4.9375"OD shaft. So basically you have a hollow shaft attached to a drive shaft, with a filler tube placed between them to fill the gap. Two 1-1/2" UNC bolts are placed in matching1.531" diameter holes in every component (thru bolted) with a nut. Tightening the nut will tend to flatten the pipes, taking up the clearance between then and creating a contact pressure on the drive shaft. I have having trouble getting all of the contacts correct since the components are not in contact at the beginning of the simulation due to the radial clearances.
Two axial bolt loads of 129,000 lbs will be placed on the tubes. I have used a sliding/no separation contact between the bolt and nut. Then I put a fixed constraint on the bottom face of the nut (not in contact with the tube) and put a 129,000 force on the top of each bolt head to simulate the axial load created by the bolt preload. What type of contact should I use between the tubes that have radial clearance?
I have attached the tubes and drive shaft. The 1-1/2" bolts and nuts (both heavy hex) were found in the library.
How to set up a symmetric stress analysis?
I read about using symmetric analysis on a symmetric assembly, but no description of how it is done.
I am trying to properly stress test a steel aircraft fuselage. I can easily model the estimated weight of the pilot, copilot, etc as loads on the airframe. However, when it comes to simulating a high-G situation, (a load factor of around 7.5 times the force of gravity), I am not sure what to do. On one hand, I can simply multiply the loads on the airframe by the load factor and see if the frame can take it. In most cases, it performs very poorly, (safety factor less than 1). However, if I model all the loads under normal conditions, (normal pilot weight, etc.), then add a gravity load equal to 7.5 G, the airframe performs well. Yet I am not sure if the loads on the airframe, (such as pilot weight), are being adjusted along with the increased gravitational load.
My question is, what is the best way to accurately simulate real world loading for high-G situations?
I am doing an eigen frequency analysis of a structure in the range of 0 to 1500 Hz. For my structure I am getting about 6 modes as expected.
For the final results I will mass normalize to convert to an energy based on the relative "displacements" However, each of the "displacements" for the 6 eigenfrequencies are the same?
I know this can not be right as it would mean that all have the same energy which is impossible.
I am trying to determine how to properley constrain the assembly below, so that the compression of the rubber gasket will be properly indicated.
Currently I am seeing the deflection of the shelf in the downward direction, but I do not see any indication of stress in the gasket behind.Currently the gasket is "bonded" to the steel tube the screws are bonded to the shelf bracket and the steel tube.
I put in "work axis" at the center line of the shelf bracket and the CL of the gasket, but I can't find a way to constrain to a work axis.The file is too large to upload here...

and it says I don't have enough memory! How can this be? Its not that complicated of an assembly. I have done bigger. I excluded all the part I'm not using and they are all basic plate and tube parts. There are less than 20 parts in the assembly.
How can do the thickness analysis in autodesk inventor like solidwiorks thickness analysis, it show the thickness of the part in point to point
View 1 Replies View RelatedI have used a few times 'Stress analysis' before. Today I discovered it is disabled. I applied a software update (SP1, build 222), after which I could run a Stress analysis again. However, Inventor crashed soon, and after restarting it, Stress analysis is disabled again. In 'Add-In Manager' the 'Simulation: Stress analysis' is shown as 'Automatic/Loaded'.
UPDATE: I have unchecked the 'Load Automatically' option for this module, quit Inventor, started it again, loaded the module and now it seems to work. I don't know yet for how long...
UPDATE2: well I could start a Stress analysis, but everything is disabled there, I can not create a simulation for example.
I 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.

View 5 Replies View RelatedI work for a tank building company and we are starting to use Inventor for stress analysis. We have a tank that we are designing that has a tank inside of another tank. The internal tank will be holding product while the outside tank is there to prevent product leakage in the event that the internal tank has a leak. There is piping that is welded to both the inside tank and the outside tank.
So here's my question: We know the radial deflection of the piping on the internal tank due to pressure, but we want to know what the stress is going to be on the external tank shell. Is there a way that I can input the amount of deflection and so that inventor will calculate the stresses involved?
I saw thermal properties in the list of Inventor's materials. However, I didn't find how to make a thermal analysis using Inventor MEF. Is it possible?
