Hi,

I am using Tang's minigeotechfoam to simulate the seabed response under the dynamic wave action.https://bitbucket.org/tiantang/minig...PlateOnSeabed/
I am not sure if I should subtract one value of pressure (might be initialstress) since there are several types of pressure defined in the model, e.g. pressure of the atmosphere, reference pressure, etc.. How can I evaluate those pressure?
How to change the parameters used in the plastic model according to the different soils? Do you have any ideas? Appreciated.

Hi, guys

I am using the tutorial with respect to twoSurfacePlaticBiotFoam. I did not understand why the initial tress (5E4) was specified in the boundary condition for dU and P, which is the initial stress induced by the upper structure gravity or something else? I tried to reduce this value and the solver was crashed while I increase this value and it still worked. Do you have any idea?
