I have tried making the mesh "fine," there are no fillets, I have chosen select all surfaces, I have tried picking each part from the design tree, and I have confirmed that changing the material applied to every part. I want one simulation at -200 C and another at 100 C. Any other trouble shooting ideas would be greatly appreciated!
Hi Margaret,
That's a good description of what you have been doing with this model but, based on your description, I am unsure what sort of issue you are facing with this model. What seems to be the problem here?
Hi Ryan,
I keep getting a message that says "temperature transfer failed" and having to completely quit solidworks. I don't know how to get it to actually run the simulation successfully.
Best,
Margaret
Margaret,
I opened your files on my end and of the studies I found ("Static extend", "Static retract", and "Static 3 tpu") I did not find any applied temperature boundaries in the models.
I ran all studies though and nothing came back with an error.
Was there another version of this design that had thermal boundaries applied in the static studies?
Here are all the files that trying to run the study produces. Originally I just posted what I knew to be working! Do these work/give you more reference?
Margaret,
I am now seeing the error you describe. The definition of the temperature boundary is not accurate when selecting faces like this in a static analysis as it leaves all the internal volume nodes with a null value that gets assigned 0 Kelvin.
When I deleted and redefined the temperature boundary selecting the bodies of the model so the nodes on the internal volume also had temperatures assigned I no longer got an errors citing the temperature transfer failure. This would be both more accurate and seems to fix the error you are seeing.
Attached is the modified set of files with a now working thermal static study for -200 Celsius for you to run and verify on your own system.
Thank you so much! I really appreciate your help. I had tried picking all the parts at one point and it didn't work, but now it is working and I was able to reproduce the effect in a separate model so I'm happy.
