[Gmsh] How to perform local mesh refinement in GMSH ?

[DILASSER Guillaume]

Dear Prithivirajan,

Alternately, you can also use fields to specify your mesh density near certain points. You might want to have a look to the Sphere field or the attractor field documentations here<http://gmsh.info/doc/texinfo/gmsh.html#Specifying-mesh-element-sizes>. There is also an example of what you can achieve here<http://gmsh.info/doc/texinfo/gmsh.html#t10_002egeo>.

Sincerely Yours,

Hello, I don't know about refinement around the sphere, but you can do it around a local point. You need to define that point and include it in volumes, surfaces or lines.
For example, suppose you have defined x,y,z,lc variables and Surface 20 numbering exists.
Point(11) = {x,y,z,lc};
Point(11) In Surface(20);

Regards.

Hello All,

I am using Gmsh for creating a finite element mesh. After I create the volume mesh, Is there a way to do a local mesh refinement around a particular point (say x,y,z) and within a sphere of given radius.

Kindly help !
