Concept Design Using Topology and Topography Optimization

Chapter 1: Topology Optimization of a Structural C-ClipDefine objective function1. Click objective.2. Verify Objective is set to min.3. Click response= and select vol.4. Click create.5. Click return twice to exit the Optimization panel.Solve the problem1. From the BCs page, select OptiStruct to access the OptiStruct solver.This panel exports the deck, runs the analysis/optimization and then loads the resultsfiles into HyperMesh after the job is completed.2. Click save as…., enter cclip_complete.fem as the file name, and click Save.This indicates to OptiStruct what file name is to be associated with the variousoutputs it creates and where to locate the files. The actual save occurs at thecompletion of the optimization run.3. Click the switch below Run Options: and select Optimization.4. Click Optistruct to run the optimization.Running OptiStruct from this panel automatically loads the results file after the job isdone. When you click the optistruct button, OptiStruct: writes out the OptiStructinput file, solves the optimization, and loads the results into HyperMesh for postprocessing.You no longer need to export the file with the OptiStruct template,manually initiate the solver, and import the results file for post-processing.The message “….Processing complete” appears in the window at thecompletion of the OptiStruct job. OptiStruct also reports error messages, if any. Iferror messages appear, open the file cclip_complete.out in a text editor to lookfor details about the error. The cclip_complete.out file is written to the samedirectory as the .fem file.5. Close the DOS window or shell and click Return.18Concept Design Using Topology and Topography Optimization OptiStruct 7.0Proprietary Information of Altair Engineering, Inc.
