By introducing additional supports to members' ends (restrictions to boundary conditions), which can be done through the Model type option of a member e.g. N-Vy-Mz, a nonconformity is displayed in the Analysis tab in Check after the calculation.
Nonconformities in the tab are summed up from all members of the model and the forces values are displayed in the global coordinate system.
These are forces that are applied in the analysis of the FEM joint model and represent the reactions generated in the additional supports at the corresponding member's free ends.
If these nonconformities exceed the inputted average internal forces more than a little (in corresponding directions and rotations), the model analysis may be inaccurate. The recommended deviation of nonconformity values is up to 5% of the inputted member forces to keep the analysis inaccuracy low.
