  2. Rename the constraint to Outer Face Fixed.
  3. Orient the model inside Autodesk Nastran In-CAD so that you can clearly view and pick the outer most upper face.

  4. Be sure that Subcase 1 is selected in the Subcases list.

  5. Accept the default settings and click OK to create a fixed constraint.
