The MSC.Nastran Thermal Analysis User’s Guide describes the heat transfer-specific material within MSC.Nastran required for performing thermal analyses. This book emphasizes fundamental capabilities, describing them in basic engineering format, and then detailing the interface to MSC.Nastran through the Bulk Data entry descriptions. A series of examples demonstrates a wide cross section of available features and their application with complete MSC.Nastran input listings.

This user’s guide is not intended to provide an exhaustive treatment of heat transfer or finite element theory. Rather, it is designed to assist in building, analyzing, and designing basic thermal system models and to numerically study their thermal performance. Some advanced material is included in the appendices to direct the most efficient use of the more complicated features.

The information contained here can be augmented with material available in the Getting Started with MSC.Nastran User’s Guide, MSC.Nastran Quick Reference Guide, and the MSC.Nastran Reference Manual as well as the MSC.Nastran Handbook for Nonlinear Analysis. These manuals can provide greater depth of coverage regarding finite element basics, modeling, input file structure, and nonlinear solution techniques. A complementary product, MSC.Patran, is available for performing pre- and post-processing functions for MSC.Nastran Heat Transfer. This engineering graphics package automates the reading of CAD geometry, automeshing of the finite element mesh, creation and application of the material properties, loads, boundary conditions, nonlinear solution control, analysis job submittal, results access, and results visualization. This product and its application are described in MSC.Nastran Preference Guide, Volume II - Thermal Analysis.

Starting with Version 68 there have been substantial modifications made to the MSC.Nastran heat transfer capability. Along with many new and flexible features, a break with the past has occurred in terms of non-upward compatible Bulk Data entries. The primary areas where nonupward compatibilities arise include the specification of CHBDY surface elements, boundary and initial conditions, available solution sequences, and temperature boundary conditions.
