Nonlinear Transient Heat Transfer (NE-L5 Module)

Overview

Nonlinear Steady State Heat Transfer

The Advanced Heat Transfer package adds nonlinear steady state and transient heat transfer to the impressive array of Nastran capabilities. Support is provided for both 2D and 3D models using solid, shell, and line element types. The heat transfer solver is fully integrated into NEi Nastran allowing heat transfer models to also be used for structural analysis. Thermal loading from a heat transfer solution is generated automatically allowing thermal stress analysis to be performed directly following a heat transfer run (multi-physics capability).
