Mesh size map feature
I would like to know if Gmsh allows to input a mesh size map to determine mesh refinement.
More precisely, suppose I start with an initial mesh, solve some problem over it, and evaluate some error measure at each mesh point. Is there any way to give Gmsh a target element characteristic length for each node of the initial mesh (a mesh size map), and produce a new mesh according to those new characteristic length specifications ?
This would be immensely useful for adaptive meshing.
