Problem when importing CAD file into COMSOL

Hello

Using COMSOL, I have imported a geometry (step file “.stp”) into COMSOL and converted it into COMSOL object.

Afterwards, the following error message keeps popping up: “Unsupported degree on Bezier representation”

Another error message that keeps popping up is: “Error in Geometry Decomposition”

What does each error message mean and how to solve these two errors ?

Thanks
Nayef
