To Explore a Topology Element Density Isosurface
1. On the Results tab, click the arrow next to the Response Types list, and select Topology Element Density. The Density Isosurface group appears.
2. Use the Design Cycles slider or box to enter the number of the design cycle for which you want to view results.
3. Under Isosurfaces, select an option:
Isosurface—Shows an isosurface that encloses all the regions where the density is greater than the lower cutoff value.
Isosurface with Topology Region—Shows the same isosurface as above, along with the topology region as it appeared before material was removed to show the isosurface.
