An issue has been reported in Advance Design 2013 SP1.

This problem occurs on torsors of linear supports : all components are affected by a « -1 » coefficient, showing « reactions on supports » instead of « actions on supports ».

This issue also affects forces on punctual supports (but only in case of dynamic loadcases with CQC summation method activated and results without sign).

For the moment, Service Pack 1 has been suspended.

A new version should be available soon.
