Processing real constants

Hello, I have a problem with a simulation in Solidworks.

I have a not too complex assembly, the mesh is done quite quickly, on the other hand the software remains stuck on "processing real constants" for quite a while, has anyone ever had the problem? I googled... not possible to find this "Processing real constants"

Thank you very much, have a good day everyone!

 

Hello

Are you sure that this is exactly the text that is being written? Because I haven't found anything either and it's very strange!

It is this text word for word, letter for letter. Strange yes!

I have two meshes on two very similar geometries. The first one everything works well. The second instead of 2 minutes solves the problem in three hours. At first it seems stuck on "processing real constants", but in reality it unblocks after several minutes and it continues very slowly. During this, and throughout the solution, it uses very little resources (less than 1% of the CPU for example). The first mesh seems to go faster because it uses at least 25% of the CPU. I can't imagine why this behavior is so different on two almost identical problems
