I have a study (asm) to test. The problem is that the mechanical welding parts are complex in shape and are not perfectly in contact with each other and sometimes interfere (not too serious because they need to be adjusted during assembly). Impossible to adjust exactly. Problem, when meshing it crashes... In this case, how do you deal with this problem? Is it better to increase the space between the rooms, even if it means no longer having contact or other methods? Thank you.
It is often impossible to carry out the studies with the parts for production. As a result, we often have to redesign parts for simulation.
Otherwise, we also use the following method:
Save Assembly as Part: Save As and then select the Part Type .sldprt
In the part thus created, select the bodies and right-click then Merge
Thus, we end up with an assembly that becomes a single part with a single body. However, the fusion of bodies often poses a problem with complex parts. Hence the obligation to redesign.
