Hello!
I have a simple model in Midas GTS NX 3d. A foundation as a 3d (solid) beam which lays on some layers of soil (constitutive model used - Modified Mohr-Coulomb/Hardening soil).
I ran the analysis and i've got the settlements which seems to be valid. The problem is when im trying to model the water level.
The site situation is: water level was initially at -6.6m depth. After the geological investigations has been done, the water level rised at -2.5m. How can i do to model this in midas gts nx 3d? I need an initial stage with water at level -6.6m, a stage where i put the foundation with the pressure on it, then a stage where water comes to -2.5m.

P.S. i've managed to do it somehow, but the results doesn't seem to be valid. After water rised to 2.5m, the settlement decreased, so, it appeared the uplift phenomena. There is not the case. The construction is an existing building. I need to see the results after consolidation.

Sorry for my bad english. Hope you'll get what i wanted to say!
I have also attached a gts file with my model.

Thank you for your future answers!
