Hi all,
We have discovered the problem and it will be addressed in Creo 3.0 M100.
In the event of such a crash, a workaround will be to check if the description field is blank for the assigned material of the model. This can be done through Creo Parametric by selecting: File > Prepare > Model Properties > Material - Change, to open the material dialog. On the right side of the screen will be the applied material. Double clicking on the material will open the material definition dialog where you will see the material details. If the description field is blank, please add some text and click OK. Now you can close the material properties dialog and access Simulate via Application > Simulate.
In the future build, this step will not be necessary, as Simulate will handle the situation when the description field is blank.
Regards,
Mark
