Hi,
after the extrusion, you can modify the characteristic length associated with
the newly created points with the command
http://www.geuz.org/gmsh/doc/texinfo/gmsh.html#Characteristic-lengths
Characteristic Length { expression-list } = expression;
Modify the characteristic length of the points whose identification numbers are listed in expression-list. The new
value is given by expression.
Regards,
Dave

Dear Gmsh-List,
I have created a cylinder by extrusion of four arc-segments, but would like one
side of the mesh to have small elements, and the other end large; Is this
possible in gmsh? I cannot see how I can use point weights to do this.
Point(1) = {0,0,0,0.5};
Point(2) = {2500,0,0,0.5};
Point(3) = {0,2500,0,0.5};
Point(4) = {-2500,0,0,0.5};
Point(5) = {0,-2500,0,0.5};
Circle(1) = {2,1,3};
Circle(2) = {3,1,4};
Circle(3) = {4,1,5};
Circle(4) = {5,1,2};
Line Loop(5) = {1,2,3,4};
Plane Surface(6) = {5};
Extrude {0,0,10000} {
Surface{6};
}
Thanks.
