Check Element Quality
After you build your model, check the quality of the elements in the model.
You can check your model for connectivity and duplicate elements.
-
Use the Check Elems panel, 1D subpanel to:
- Check one-dimensional elements for free ends
- Determine if a group of rigid elements form a loop
- Check weld and rigid elements for double dependency
- Check all elements for a minimum length of a side
-
Use the Check Elems, 2D panel to:
- Check elements for warpage, aspect ratio, skew, and jacobian ratio
- Check the maximum and minimum interior angles of quad and tria elements
- Check all elements for a minimum length of a side
- Check a mesh of elements for its maximum chordal deviation from a real or inferred surface
-
Use the Check Elems, 3D panel to:
- Check elements for warpage, aspect ratio, skew, and jacobian ratio
- Check the maximum and minimum interior angles of quad and tria elements
- Check all elements for a minimum length of a side
- Check tetra elements for collapse, CFD-style volumetric skew, and Nastran-style aspect ratio
- Use the Check Elems, Time subpanel to check for elements whose small size might cause problems for an explicit solver.
- Use the Check Elems, Group subpanel to check for and eliminate group or interface elements whose underlying structural element has changed and left them detached.
- Use the Check Elems, User subpanel to verify element quality by using a template file that checks for user-specified conditions.
