As many numeric simulations are mesh based approaches, a domain decomposition into triangular elements is a essential process in order to produce a good representation of the target domain. But, many methods were proposed and the commonly used approaches have different behaviors depending of the domain to mesh. Convex domains are easier to form good triangulations by most methods because of the well formed borders, but non-convex domains may be a problem to represent correctly. This paper performs a qualitative analysis of two known triangulation methods, the Ruppert and Force Balance refinement methods. We present some results of mesh refinement for non-convex domains by testing the minimal restriction angle.
