Dear all,
I’m creating a 3D mesh using a geo file from Gmsh. Some labels (integer numbers) defines the boundary surfaces, and it works fine for Dirichlet condition with solve:on(label,condition).
For Neumann condition, I would like to use the argument Region of the int2d function:
int2d(Th, Region) ()
Apparently, the label from Gmsh cannot be used directly since it creates an error.
Thus my question, how to create a Region from a surface defined by a label out of Gmsh.
Thanks for your support
Dominique
