Question

I am trying to solve a PDE on a regular mesh on the unit square. I found the regular mesh generator poimesh, which seems to do the job, but I cannot see how to create a geometry file for the unit square. So my question is:

How do I create a geometry file for the unit square in Matlab?

Answer 1

To create a unit square geometry, you can do the following

g='squareg'; % The unit square
[p,e,t]=poimesh(g, nx, ny);

I realize this is not so easy to find. Have a look at examples and e.g., here
