Dear Michael, The problem stems from the "Transfinite" meshing constraints: the automatic "Transfinite Volume" command (i.e. when the corners of the transfinite interpolation are not provided) does not guarantee that the volume and surface meshes will match - it should thus be used carefully.

Dear Christophe, we have questions to your article "A frontal approach to hex-dominant mesh generation". We also tried to use gmesh for meshing existing CAD-data from the homepage cited as Reference 41 in the above mentioned paper. But, gmesh generates error messages concerning penetrated surfac

Dear Christophe, I need your help with an error in gmsh. Using 10-node tetrahedron elements for discretizing a cook-like cube (see attached file), I get two nodes 36 and 37, which should not exist. These nodes arise not in the volume elements, but in the surface elements, and therefore in the no
