Modeling soil in ANSYS workbench v14.5: Problems using Drucker Prager via APDL commands
Modeling soil in ANSYS workbench v14.5: Problems using Drucker Prager via APDL commands
(OP)
For my master thesis I have to construct a model of a tower and it's underlying soil using ANSYS v14.5.
For now, i have made a foundation slab embedded into a layer of soil. I have no trouble converging to a solution by defining the soil using only it's density, elasticity and poisson factor.
However as soon as try to include Drucker Prager (defined by cohesion, internal friction and dilatancy) by using APDL commands onto the solid "soil" geometry volume, it doesn't converge anymore.

Anybody have experience modelling soil in ansys?
