M. To check for negative volume solids

To check for solids that would result in a negative volume in the analysis, do the following.

This check uses the Jacobian matrix determinate to determine if any of the solids have a negative or indeterminate volume, which would result in an analysis error.
  1. On the Utilities ribbon tab, select the Solid Tools > Negative Volume tool in the Geometry Tools group.

    The List of Solids dialog opens.
  2. Select any solid number in the list to select it in the view window.
  3. Click Close.
