Criteria Settings
Overview of the criteria settings used in QI (quality index) and batch meshing, and in QI-based element checks.
Configure criteria settings using the Criteria Editor. Criteria settings can be saved to a file, and loaded for subsequent editing.
- Access
- Right-click on the Element Quality legend and select Edit Criteria.
Switch between 2D and 3D criteria from the tree on the left of the dialog.
- Target element size
- Desired element size for the mesh.CAUTION:Modifying this value may generate errors in the Min Size and Max Size, which will show up as red text.
- Row Up, Row Down (, )
- Change the display order of criteria in the Element Quality Criteria
legend.Tip: If you change the order of the element criteria after you have adjusted the threshold values in the Criteria legend, the threshold values will reset to their fail values. It is best to change the order of the element criteria first, and then change the threshold values in the Criteria legend.
- Calculation method
- Select the solver to be used when calculating criteria checks.
- Time step calculator ()
- Minimum length calculator, based on TimeStep, which can be used to calculate the suggested minimum length, based on a material, time step, scale factor, Young's modulus, Poisson's ratio, and density.
- On
- In the On column, use the checkbox to turn each individual check on/off.
- Color
