<p class="MsoNormal">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.<o:p></o:p></p>

Hello All,<br>
<br>
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.<br>
<br>
Kindly help !<o:p></o:p></p>
