Notes

- Checking is done for the element ends (cross sections or solid sections) of selected elements at the moment of command execution.

- All calculations are performed according to the active code (see ~CODESEL command).

- The description of the calculation process used can be found in the Theory Manual.

- The analysis results are stored in CivilFEM results file as an alternative.
