 MWDAM-1227
 As with MWDAM-1219 the real problem is the correct determination of the Location With Lowest UpliftFactor. Old DAM uses (wrongly) global surface line whereas the engine uses the correct localised surface line. The effect here is a different value for xCoordinateLastUpliftPoint which is passed on to the DGSMStabDam.dll which determines the grid.

+DAM 15.1 always calculated with Psi=Phi since Psi wsa no input in D-Geo Stability 15. Later versions of D-Geo Stability (also 18.1) consider Psi as input. Also DAM 18.1 always calculates with Psi=Phi. Note: When *.sti files are used with a different value for Psi are 'reset' to psi=phi.

 MWDAM-1238
 Piping design calculation with geometry adaption gives wrong safety factor in result in release 15.1.
 This issue has been solved, so the safety factors in design calculation with geometry adaption will be different than in the 15.1 release version. The new answers are the correct answers.
