Postprocessing in FEM

Postprocessing in Finite Element Method

Once the finite element matrix equations are solved for field values at the nodes, in postprocessing these derived quantities are graphically displayed. To know the variation of the field variable along the model/mesh contour plots of the field are plotted.The present code is useful for postprocessing of 2D and 3D finite element analysis. After finite element analysis is done for the nodal field values, the present code can be used to plot the contour plots. The contour plots can be plotted on the mesh and also on the deformed mesh. The input required are the field values along with the nodal coordinates and the node numbers connecting the elements.
