Internal error in geometry composition, Comsol 4.2a

Please login with a confirmed email address before reporting spam

Dear Fellows,

I want to make blocks with round edges in 3D. I use standard procedure, I define workplanes, make geometrical objects in 2D, do "extrude", end on the end - INTERSECTION.

When I do these steps in Comsol 4.2a version 4.2.1.110 (older version) everything is OK, but when I do the same in

Comsol 4.2a version 4.2.1.166 (newer version) I receive message:

"Internal error in geometry composition"

Please if someone have a solution for this problem because I need to solve this in newer version because on workstation on which I work is the newer Comsol. I tried to make this module in older version and then to open it in newre version, but then I receive some message about problems with CAD import module.

Thanks in advanced.

this error often means that the programm doesnt like certain boundaries to touch/overlap with each other. just create a minimal gap between each geometric object to get it to work and then search stepwhise for the bugged area by removing the gaps one at a time
