Hello, I would like to do some calculations on the unit square using criss-cross meshes. Is there a simple way to create such a mesh on a unit square? Thanks!

Do you mean a mesh like this? [crisscross]

It should be quite similar, but I think it isn’t the one you plotted. The procedure that I want to use can be described as follows: partition the domain into triangles by first subdividing it into squares with sides of length 2h (here h is 2^(-k), k integer). Then dividing each of these squares fi…

in freefem just do: mesh Th = square(n, m, [x0+(x1-x0)*x, y0+(y1-y0)*y], flags=1);// build a will produce a Union Jack flag type of mesh or criss-cross meshes.
