Others speak of "conforming"; "conformity" (like gmsh man) one reads. Guess I goes all down to the very same, does not it? But then there is extra info such as region, or boundary by. There the question is: If there is a standardized format to be be qualified as "conformal"? This mean basically ready for solving. How would such a mesh preparation state be called? Not at all? Well and then there was found a definition, where the claim to have a patent on http://www.sonnetsoftware.com/support/help-current-version/help_topics/what_is_conformal_mesh_.htm conformal meshing: "Conformal meshing is a technique which can dramatically reduce the memory and time required for analysis" Could you please help to sort those terms in? tia.
>If the OCC functions for connecting/sewing faces work only for flat faces as >suggested in the thread you cite, they are next to useless since curved faces >occur in 3D. It is rumor... It seems that at the moment only Salomé can sew such faces - but AFAIK Salomé uses OCC also, so there must be a way... Would be a help, if some gmsh experts could drop a commentary on: (As I see there are several ways of representing and controlling multiregion (zones,bodies), thus importing and exporting signaling. -Given the cited command line where along do the ready-to-solve data flow? And what is the typical problem about it all, if there is? >gmsh face_com_step.step -2 -format unv -o compound_of_faces.unv -optimize >-string "Geometry.OCCSewFaces=1;" -string "Mesh.CharacteristicLengthFactor = >1.5;" -What is about "Names" of such "Groups" for the (external) solver to identify? How are they introduced? -And yes, what is about bespoken unflat interboundary faces, can gmsh handle it multiregionally or can it not?
