Mesh refinement support from Gmsh library #40

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
At the moment mesh refinement is supported through system call to Gmsh 
executable.
it should also be supported by the library and done before partitioning

Provided that gmsh is correctly detected it "should already be" the case.
That's what we use here in Grenoble at the LNCMI.

Try to gmsh-tetgen instead of gmsh on Debian sid should fix the issue.
On other platform gmsh needs to compile with tetgen, mmg3d support.

Beware that gmsh package has been split into several packages on Debian 
unstable : gmsh, libgmsh-dev, libgmsh2, python-gmsh and maybe java-gmsh.

Same should apply to gmsh-tetgen.

Mesh refinement should be understood as element splitting not mesh adaptation
which would be overkill for this task.
In the case of convergence analysis it would be better to generate mesh using 
element splitting. It would be much faster than any other techniques. One more 
thing is to generate also very fine meshes in 3D for parallel computations 
instead of asking for a global characteristic mesh size that the mesh generator 
takes ages to generate.
Of course one  could also use mesh adaptation.

use element splitting to refine the mesh for convergence analysis
