The Finite Element Method has its advancement over other finite difference methods due to taken into consideration the irregular shape domain of problem. The domain of interest on which problem is defined has to be subdivided into sub domains. Herein, two irregular-shaped domain are considered and elliptic equations are solved in each domain with the boundary conditions having varies nature i.e. Dirichlet, Neumann and mixed conditions are applied. Detail discretisation of Finite Element Method and Weighted Residual Techniques are also discussed with their prerequisite conditions. So this Method is a novel fast elliptic solver that can serves as a feasible alternative for numerical solutions and the results compare well with those of [18].
