A user controlled interactive computer graphics postprocessor for two-dimensional static and dynamic finite element analysis is developed. This post processor is a menu driven interactive program. This post processor supports more than 50 graphics devices. This program can manipulate the original finite element mesh data, displacement, stress, strain and up to four other values such as temperature. The user can choose any one of the following methods to display the values: Deformed mesh, Vector flow, Color Contours or Curved Contours. With this postprocessor, an improved contouring algorithm is proposed specially for finite element method. This algorithm uses the same isoparametric element representation as used in the analysis stage. That means the contour curves are accurate assuming that the nodal values are accurate and the real values inside the element can be interpolated by the element shape functions. So, this algorithm provides a continuity as the same order as that of the shape functions used for the finite element.
