Hi,

I am trying to run a co-simulation Q3D and Icepak for a power module to correlate the parasitic losses with the thermal thing. I have given the EM loss boundary condition in Icepak for the model. However, meshing is not taking place and the software crashes. I tried coarse mesh and this crashes by mentioned warnings like 'this geometry does not have mesh'. I tried healing and simplifying the model, even then no chance. I imported the geometry from AutoCAD as an iges file. some portion of the geometry is from the iges file and the remaining, I copy pasted from an already existing .stp file with in the ansys window. and then deleted the unnecessary. I did this because, when importing from AutoCAD, the objects are imported as sheets and not solids/ volumes in ansys. what do you suggest?

Thanks for asking questions on forum. If geometry is very complex with many curved surfaces, objects may not be properly imported as solids. For these objects imported, you may need to use Spaceclaim to fix them. For the meshing issue, if the objects are thin or have small diameter, you may need to use mesh operation along with multi-level meshing to mesh them properly. If possible, please submit a support case to get your model checked. Thanks.
