Concept Design Using Topology and Topography Optimization

Chapter 2: Topology Optimization of an Automotive Control ArmStep 2: Set up a check run for OptiStructDuring the check run, OptiStruct checks the syntax of the input deck, calculates arecommended amount of RAM, and estimates the required disk space for the model.OptiStruct also scans the input deck verifying the parameters required to run theanalysis and optimization.1. From the BCs page select OptiStruct.From this panel you can export the deck, run the analysis/optimization, and thenafter the job completes load the results files into HyperMesh. A check run can alsobe performed from this panel.2. Click save as…, enter carm_check.fem as the file name, and click Save.3. Click the switch below Run Options: and select Check.4. Click optistruct to run the check run.The check run for this model should take approximately 5 to 10 seconds ofprocessing time.Once the processing completes, view the file carm_check.out at the UNIX promptor through a Windows utility. The OptiStruct output file contains specific informationon the file setup, the setup of your optimization problem, an estimate for the amountof RAM and disk space required for the run, information for each optimizationiteration, and compute time information. Review this file for possible warnings anderrors that are flagged from processing the carm_check.fem file.5. Close the DOS window or shell and click return.38Concept Design Using Topology and Topography Optimization OptiStruct 7.0Proprietary Information of Altair Engineering, Inc.
