I am trying one problem of Seismic response analysis to a Block type Deep soil -pile model .This DSPM is nothing but Engineered soil-cement mix which will give me at least 10mpa compressive strength with a dimension of the block 24mx24mx25m deep in a Elastic soil.The size of the Soil Boundary 75mx75mx50m. Now If I model these components using Ansys2020R1 .Here the Boundary soil may be Moderate strength Clayee soil having Subgrade stiffness=5E+07N/m3

1.How do I put the Absorbing Boundary condition using Ansys2020 R1

The INFIN257 element (in APDL) can be used outside the elastic soil to represent an infinite structural domain.

Thank you dlooman for your suggestion. I will revert back shortly.But will this element will act like an interface element which can be glued to the outer face of the soil contoniam ?

Sorry I meant Soil Continuum.

Dear Dlooman I have gone through the Ansys Element INFIN257 from Ansys Mechanical element ref doc and noted that I have to develop these elements as an additional layer over my soil elements(Solid 186 which is already modelled ).But I am not getting any reference of APDL command lines to do this job as the command lines to develop INFIN257 is required to be known for inserting the same.I will be grateful if you can throw some light.
