1 WORKSHOP 20 SINDA TRANSLATION OF A PWB MODEL
2 WS20-2 PAT312, Workshop 20, December 2006 Copyright 2007 MSC.Software Corporation
3 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.
4 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.
5 WS20-5 PAT312, Workshop 20, December 2006 Copyright 2007 MSC.Software Corporation Exercise Overview: 1. Create a new database named exercise_20.db. Set Tolerance to Default, and the Analysis Code to MSC/THERMAL. 2. Use File/Session/Play… to read exercise_20. ses file and create the analysis model of Figure Prepare and submit model for analysis selecting Submit Option/Create SINDA File (model.sin). 4. Modify the Select Results File… filter to retrieve nr0.sin. 5. Modify the Select Rslt Template File… filter to use the sinda.res_tmpl template. 6. Plot SINDA/G results. 7. Go to the Job Name subdirectory to review the contents of model.sin Quit MSC. Patran.
