Select the region to restrict the movement. Create set or select a created set. Restrict laterals and bottom facesin the perpendicular direction to the set.

MODULE: INTERACTIONS

Create an Interactions properties. Select Contact Type. In tangential Behavior set Friction coeff 0.3 and in NormalBehavior the Pressure Overclosure option set “Hard” Contact

In Interactions option select Find Contact Pairs to auto-detect the contact pair surfaces in the parts.

Click on Find Contact Pairs. Select a candidate and whit the Highlight in the viewport option selected to see itin the viewport . Change the Bottom Interaction Type to Tie.

Double click on Adjust box, click on Adjust Only to remove overclosure, do it for the others Contact Pairs.Press OK to generate the interactions.

Create a new constraint. Change the Type to MPC Constraint.

Create a new Set, Select in the Viewport the MPC Control Point

Select the Region for the Slave Nodes in the viewport. Change the MPC type to Tie.

MODULE: STEP

In Initial Step Create a predefined field. select Step Initial and in Mechanical Category select Geostatic Stress.

Select Set…, in the Eligible Sets choose one.

Introduce the stress magnitude in the coordinate 0 is 0 and 10 is -200. Use the same coordinates and stressmagnitude for the pile. The lateral coefficients are 0.5 in soil and 1 in pile.

In the Geostatic Step Create a Load. in the Category Mechanical select the Gravity.

Set 0 in Components 1 and 2 and 10 in Component 3, the distribution is Uniform.

In Load step Create a new Boundary Condition (BCs). select in Mechanical category Displacement/Rotationoption.

Select the MPC Control Point.

Set 1 m Displacement in U3 direction with Uniform distribution and (Ramp) Amplitude.
