Concept Design Using Topology and Topography Optimization

Chapter 2: Topology Optimization of an Automotive Control ArmStep 4: View result using HyperView Player1. Go to the current working directory and locate the file carm_complete.html.2. Right-click carm_complete.html and select Open.The system web browser application (Netscape or Internet Explorer, for example)initializes displaying the OptiStruct report in HTML format.3. Review the HTML report.4. From the results summary section of the report, select the blue Click here hyperlink.This displays the OptiStruct H3d in HyperView Player. You can select the simulationtype, result type and simulation id to review results.5. Exit the web browser application.Step 5: View results using command filesOptiStruct creates two HyperMesh command files carm_complete.HM.ent.cmf andcarm_complete.HM.comp.cmf that could be used to organize the elements into entitysets and components based on their density results values.1. From any page in HyperMesh select the files panel.2. Select the command subpanel.3. Select the file carm_complete.hm.ent.cmf.4. Click execute.5. Repeat steps 3 and 4 for file carm_complete.hm.comp.cmf.6. Click return.7. Press F5 to activate the mask panel.8. Click elems and select by sets.9. There are 10 different entity sets from 0.0-0.1, 0.1-0.2, 0.2-0.3 and so on.10. Select the entity sets 0.0-0.1 and 0.1-0.2 and click select.11. Click mask.Only elements with densities above 0.2 are displayed. The elements with densitylevels greater than 0.2 may be masked also using the masking panel and theappropriate entity sets.12. Click Unmask all and click return.13. The elements with different density levels grouped into different components may beobserved by clicking disp on the permanent menu and turning off the components0.0-0.1, 0.1-0.2 by right clicking the check box.14. Click return.46Concept Design Using Topology and Topography Optimization OptiStruct 7.0Proprietary Information of Altair Engineering, Inc.
