Hi,

It seems that all I do at the moment is ask awkward questions abot SolidWorks. Here's another one.

I've got a thermal Simulation task for which I'm using a multi-body part.

It was going fine, seemed to work OK. But then I added another two bodies and it has stopped working. Every time I try and run it tells me "Please define Thermal conductivity in material properties". But I can't find which material is missing this.

I've tried a few things like excluding nodies from the analysis or setting the material in Simulation but I can't find any pattern to what's happening.

I've even tried deleting the bodies that I'd added when it first started to fail, but I can't get it to go back to where I was. Unfortunately I didn't back up adequately. I thought I heard of a way of stripping Simulation data from a part file, but I've tried the way it worked for me before and it's not working this time.

Is there some limitation on the number of different materials you can have in a multi body part for Simulation? Or am I doing something else wrong?

When I tried running a Static load case on the same part it told me that an Elastic Modulus was missing.

The study was initially done as 2D simplification axisymmetric but I've tried full 3D without any improvement.

Any suggestions would be appreciated,
