WS20-3 PAT312, Workshop 20, December 2006 Copyright 2007 MSC.Software Corporation Objective: Create a model by playing a session file. Produce a run-ready SINDA/G deck from the model and post-process the SINDA/G temperature results.

WS20-4 PAT312, Workshop 20, December 2006 Copyright 2007 MSC.Software Corporation Model Description: In this exercise you will read a session file which will construct a board level PWB (Printed Wiring Board) heat transfer model. When the session file ends it will have produced a model that is ready to analyze. You will run the analysis in MSC.Thermal but you will also produce a run-ready SINDA/G deck. Since the platform on which you work this exercise may not have a SINDA/G executable module, results from SINDA/G are provided. With the possible exception of actually running the SINDA/G analysis, you will have used MSC.Patran to produce a syntactically correct SINDA/G deck and read in the resulting temperatures.
