I have had this problem on multiple occasions in the past and was hoping that one of you folks might have a solution.
When I have a hollow part, where the hollow volume is completely enclosed, SW Simulation will sometimes mesh the hollow volume instead of the material volume.
The workaround I have used in the past is to cut an insiginifcant hole into the hollow volume so that the hollow volume is no longer completely enclosed. This method works, but I don't like this workaround and was hoping for a better solution.
Thanks in advance.
