Hello

I’ve recently started using the 2.5.2 version and noticed a problem I wasn’t encountering on 2.5.1.

I have a model containing bolts, modelled as a split shaft, both parts as a compound part and then adding a boundary layer to apply a pretension.

That works fine but when I remesh the geometry and create the boundary layers again, the solid section turns red and I have to select the parts again. The solid section is fine up until I recreate the boundary layers, and turns red afterwards.

This also seems to happen without remeshing, simply by creating a boundary layer after the definition of the solid section.

I was able to recreate one case, and I have fixed a couple of bugs. The fix will be available in the next version.

Please confirm it works as expected.

Yes, I tried with 2.6.0 RC3 and the bug doesn’t happen any more. Thanks!
