Gradient mesh on a surface

I need to perform a gradient mesh on a certain surface. I cannot figure out if it is possible. Could be very useful if you can address me in understanding if the software can build a gradient based mesh topology.

If I understand you correctly, you want to create a mesh that is finer at one part of the surface and coarser at other locations. Is this correct?

This can be done by biasing curves. For example, copy and paste the following into the command line at the bottom of the Trelis window.

reset
brick x 10
curve 2 12 interval 10
curve 2 12 scheme bias factor 1.50 start vertex 2
curve 4 10 interval 10
curve 4 10 scheme bias factor 1.50 start vertex 1
mesh volume all

Biasing is set on curves using the Mesh>Curve>Mesh panel.
