Infiltration in partial saturated soils

Infiltration in partial saturated soils

Infiltration in partial saturated soils

(OP)
Hi.I'm simulating the evolution of the saturation index in an embankment after its consolidation(done in a situation of fixed saturation at 0.5 and pore pressure at -1000kPa).The job aborts during the step in which I deactivate the boundary condition of -1000KPa, I create a condition of zero pore pressure and I put a liquid load on the top.I think it is a problem of excessive deformation but I don't know how to solve it. Could you help me?

RE: Infiltration in partial saturated soils

first can you try increasing the material strength (stiffness) to make sure if it is excessive deformation problem or not?

I have already tried with the way you suggest with a perfect elastic material and the job, even if very slowly and with many warnings due to plasticity divergence,has been completed with reasonable results.
