Fixing Parabolic Elements
When you select the Parabolic element shape on the Run FEM Analysis dialog box, Creo Simulate selects the Fix Elements check box by default. Creo Simulate slightly straightens excessively curved edges of solid and shell mesh parabolic elements by moving the mid-edge nodes off the part geometry to a setting you determine, using the mid ratio and distortion mesh check. Note that using this approach improves mesh quality, but at some expense to the mesh's geometric accuracy.
Alternate methods of improving mesh quality include:
performing additional mesh improvement passes
establishing tighter local mesh control in problem areas
