Finite element boundary conditions
WebConclusions. Boundary conditions in finite element analysis of electrical machines are generally quite straight-forward. When generating the mesh, it is asvisable to generate … WebThe boundary conditions are of Dirichlet type, assuming, as I just said, that the flow is unperturbed. Left boundary is a free outflow, so it is to be considered as a far field …
