[Gmsh] Conformal mesh on two parts

[Krzysztof Bzowski]

Thank you for quick reply.
My example with cubes was very simplified - created to explain the 
problem. In practice I have a lot more complicated shapes, but general 
idea is the same.

I have attached STL files to this email. They should work now.

Best regards,
Krzysztof
