Hello, i am not very well conversant with MAthematica. But I want to solve a problem with the Mathematica. It is as follows. I have to draw a mesh of triangles. The mesh may not be isotropic in 2D( perfect 2D mesh = identical equilateral triangles joined to one another forming a hexagonal lattice structure). The mesh I desire mostly should consist of identical equilateral triangles joined to one another but few of the triangles should be isosceles . This would introduce inhomogeneity into the 2D lattice structure. I hope I have made myself clear. This is actually a practical problem as we see such structures when magnetic field penetrates certain type of Superconductors. If anyone can provide me some hints of how to progress I would be extremely grateful.
