Software for Finite-Element Analysis of Thermoelasticity

The P-Finite Element Integrated Thermal-Structural Program (PITS 2D) solves the equations for the combined effects of thermal expansion and elasticity in a two-dimensional or an axisymmetric three-dimensional structure. The name of this program reflects the use of p-version finite elements, in contradiction to the traditional use of h-version finite elements. In comparison with older finite-element programs that utilize the h-version, PITS 2D predicts physical response more accurately in the presence of large gradients.
