Abaqus Pile-Soil Interaction 1

[salam1980]

I hope someone can help me here. I am trying to model Pile-Soil interaction. I know how to build the model. According to Abaqus manual, for problems with soil, geostatic step has to be used and this is what I am using. I also apply gravity to my model. In the Initial Step, I apply BC+Geostatic Stress + Interactions, in the next step , which I call it Geostatic step I apply Gravity. I have checked my Units, I have changed mesh density , I have used very small time increments , in the surface to surface interaction I tried to change options, I used finite sliding , then small sliding, then I applied initial clearance , in other words, I tried many things, but my model still not working. I get messages related Singularity , Large strains, Creep and plasticity problems, Can someone please help to run this model properly please?

I hope someone can help ....
