Subject: Enable Backward Compatability and Correct Mappings 3D meshing
X-Git-Tag: V9_8_0a1~4
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=877231c43d7c454cdff56821fbdcc42df5400822;p=plugins%2Fgmshplugin.git

Enable Backward Compatability and Correct Mappings 3D meshing
- NEW 1: New algorithms for quad meshing (simple, blossom,
simplefullquad, and blossomfullquad)

- CHANGES 1: This commit allows compilation of Gmsh 4.1 &
Gmsh 4.8
