Hello, In the version 1.65.0 of GMSH, we had 3 choices for the 2D mesh algorithm : isotropic, anisotropic and triangles. From the 2.0.0 version, we only can choose between MeshAdapt and Delaunay. What are the differences? Has the isotropic algorithm disappeared? Or only changed his name? Is it possible to re-include it in the next version of GMSH? Thank you. Cecile Giorla.
