[Gmsh] Error when switching from Built-In to OpenCascade Factory

[Martin.Raedel at dlr.de]

Hello,

I just recently tried to switch from the built-in Factory to OpenCascade to use Boolean operations.

However, all of my tests involving more than one surface crash after the switch with the same error:

OpenCascade wire or line loop with tag 2 already exists

The same error occurs for all other surfaces except the first.

I added a simple brick geometry example. In case I comment out "SetFactory("OpenCASCADE"); " everything works fine. If I use the line, the errors occur.

Can someone please point out what causes these errors and how I can fix them?

Best regards
Martin Rädel
