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.
