Dear team STKO,

There are some generic questions of mine. Suppose we want to apply a ground motion (GM) (downloaded from the PEER website) at the base of a soil continuum model.
1/ As most of the GM records are recorded at the surface, to use that GM data at the base, deconvolution is to be done ...

Dear Team STKO,

What is the meaning of the following error:
"FATAL:second_order_eqn: Complex roots.
when moving active surface.
B2=8.34901e-23 4AC=9.37715e-23"?

NB: I am conducting a ground response analysis under seismic loading.

I see. Thank you for the information.

Hello team STKO,

Could you kindly clarify the significance of element thickness in plane-strain elements? I tried searching this forum, but there is not much information regarding this topic. I carried out a 2D pile-soil interaction analysis and tried to validate the model with an experiment. At ...

Thank you for your reply. I have sent the files to the mentioned email ID. I request you kindly look into the files.

Dear STKO team,

Please reply to my queries.

Hello team STKO,

I am simulating a single pile-soil centrifuge test carried out by Gohl (1991) for validation purpose. I have tried both 2D and 3D models and here are a few doubts regarding the problems I am facing.

1. In 2D model, I cannot use beam-to-solid-coupling right? Because it is made for ...

Thank you for your reply.

If at the bottom interface you have bedrock, just create 2 ASDAbsorbingBoundaryMaterials, one with the soil properties (sides) and one with the bedrock properties (bottom)

Ok, I will do it.

We are planning to update the source code of the ASDAbsorbingBoundary in ...

Please reply to my query. Thank you.

Hello team STKO,

As it is known to us that STKO's automated LK boundaries automatically identify the bottom and side boundaries. Since the bedrock shear-wave velocity and density are much higher than the soil, and the material for LK boundaries is defined only for soil, I wanted to know how STKO is ...
