Hi everyone. I'm a new user working on soil-pile analysis in Abaqus Standard. In both cases, I used 3D solid to model the soil and the steel pile. The first case involved modeling a 1-meter diameter, 20 m length, and circular pile. I successfully set up pile-soil interaction, applied a lateral load on the pile head, and ensured proper boundary conditions on the model. I used geostatic stress conditions for the initial stress. The stress (S) output appeared consistent and seem accurate.

In the second case, I modeled a smaller 0.5 meter diameter, 10 m length of circular pile. However, I encountered inconsistent stress output in this model. The stress distribution didn't follow a linear pattern as in the first case. I'm seeking guidance and assistance to understand and address these inconsistencies in the second model.
