WebNote. Adding the named parameter flags = icase with icase:. will produce a mesh where all quads are split with diagonal \(x-y=constant\). will produce a Union Jack flag type of mesh. will produce a mesh where all quads are … WebFreeFem++ is an implementation of a language dedicated to the finite element method. It enables you to solve Partial Differential Equations (PDE) easily. Problems involving PDE from several branches of physics such as fluid-structure interactions require interpolations of data on several meshes and their manipulation within one program.
