I am trying to perform a Nonlinear analysis on a rather simple shell model but there is a bug within the interface of the program.
I am running Mechanical 2014 SP1 64Bits.
The part is a surface with the following setup:
In the Element Definition Dialog, I select:
Which basically is:
- Selecting Von Mises with Isotropic Hardening
- Inputting 37.5mm as the thickness of the plate
- I then hit OK
If I go back to the material definition, the thickness is weirdly defined as 1mm, ignoring my changes.
Can anyone please confirm whether this is a bug or not?
Things I have seen:
1- If Isotropic is selected, the thickness of 37.5 is retained.
2- If Von Mises Curve With Isotropic Hardening is selected, the thickness of 37.5 is retained.
I also attached the very simple model so you guys can try it out.
Solved! Go to Solution.
I can confirm that this is a bug that we are aware of and are working on resolving. There is no ETA on a fix; I can only recommend keeping Simulation up-to-date. I apologize for the inconvience.
Please marked this as solved if your question has been answered.
There have been cases where the solver used the proper input even though the interface would show a "default" value when you re-edit the input. So the question for you scudelari is whether the results are based on a thickness of 1 or the value that you enter?

Unfortunatelly I have to say that the value does come back to 1mm after I close the first dialog.
I checked it with the display element thickness in the Results environment.
As a work around - at least for my model it was possible for the 2D nature of the model - I selected element type 2D, which does work.
As I said, I also found out that with the Von Mises Curve it keeps the thickness value, therefore one may use that as a workaround for the time being.
