Sažetak
The boundary value problem for eliptical differential equation of second order was solved by FEM with simplex finite elements. The discrete solution of higher accuracy was obtained using a superposition of proper number of such solutions on different meshes. The parameters of superposed solution were determined using the parameters of the meshes taking a part into superposition. The error estimate in the max-norm depends only on the smoothness of the right hand side function. Some examples are given for superposition of the FEM solutions for six different uniform meshes.
