WS18-3 PAT301, Workshop 18, October 2003 Problem Description In this exercise use the results for a clevis model which was analyzed using MSC.Nastran. Create various Insight tools to display the results of the analysis. The tools to be created are for iso-surfaces, contour lines, fringes, and flat planes upon which results can be displayed.

WS18-4 PAT301, Workshop 18, October 2003 Suggested Exercise Steps 1. Create a new database called clevis.db. 2. Read the OP2 file and import the results along with the model. 3. Create an Insight Isosurface tool of von Mises stress. 4. Modify the Isosurface tool making the isosurfaces 90% transparent. 5. Unpost the Isosurface tool. 6. Create an Insight Contour tool. 7. Dynamically change the minimum, maximum, and number of levels of the current range for the Contour tool. 8. Unpost the Contour tool and create a new Isosurface tool defined at X-axis coordinates. This Isosurface tool is a set of flat planes without any results displayed on them. 9. Create a Fringe tool of von Mises stress and post it on the Isosurface tool consisting of planes. 10. Unpost fringe and isosurface(plane) tools. 11. Create another isosurface(plane) tool consisting of one plane. 12. Create a fringe tool and post it on the single plane isosurface tool, then move the plane along the X-axis. 13. Quit MSC.PATRAN.
