Patran Thermal is a automated thermal modeling and analysis system for the solution of steady-state and transient problems. It is a fully-integrated analysis preference in Patran, providing an easy to use forms setup environment that guides the user to perform a successful thermal analysis. Patran Thermal has built-in viewfactor and flow network programs that use the same Patran finite element model, eliminating duplicate modeling. Patran Thermal features a large temperature-dependent materials library, extensive built-in functions and a convection correlations library. User subroutines can be added in the initial problem setup to meet the requirements of specialized applications.
