problem with periodic surface of an imported stp file
Hi, I create the geometry file .stp by using CATIA and i import it to gmsh. when i set the function periodic surface in order to have similar meshes :
boundS13[] = Boundary{Surface {13};}; boundS17[] = Boundary{Surface {17};}; Periodic Surface 17 {boundS17[]} = 13 {boundS13[]};
