Dear STKO Officials:
Hello, this is a 240m 3D field model. I am trying to simulate pile-soil interaction (SSI) using zero-length units, but it starts to get stuck at the analysis stage of adding[url] zero-length elements. No incremental steps appear in the command window for a long time, but the ...

Dear STKO Officials：
I used the calculate command from the cmd window that you recommended. But my computer reports an error. This error is the same as the one reported in the error software. It should be related to the fact that my computer cannot calculate in parallel. This problem has been tying ...

Dear STKO Team,
Hi! I have another question. In my model, there are positive and negative signs in the pile bending moments extracted as described above. What I want to know is how the positive and negative sign of the pile bending moment is defined in STKO?

Best wishes,
Charon

Dear STKO Team，
Hi,I am using STKO for 3D numerical modeling of a pile foundation with superstructure. Now there are some questions I want to ask you guys about extracting the bending moment results of the piles.
The Physical Properties used for my piles are Elastic+BeamSectionProperty and the ...

I have also encountered the same issue: The curve of the soil pore water pressure is also strange, as the pore water pressure does not rise with vibration. Have you managed to find a solution?

The surface layer of the soil has to fix the pore water pressure.
The permeability coefficient of the ...

Dear STKO Team，

Thanks for your quick reply!
Do you have any suggestions on the parameters for ZeroLengthContactASDimplex Element when acting between the pile and the soil?
I browsed other posts and I know that Kn and Kt should be quite large, as you set Kn to 1e10 and Kt to 7.14e7 in Webinar25 ...

Just extract the acceleration (relative) and sum the applied uniform excitation.

That is, the acceleration results extracted by STKO plus the results of the applied seismic waves?
In geotechnical engineering, do we mean absolute acceleration (those acceleration time graphs in the paper)?

4. The acceleration results of my analysis runs show a weird trend（As shown in the picture）. The acceleration at the deepest part of the soil is quite small, and the acceleration at the shallower part gets larger, which I know should be the rule, but the acceleration peaks at the deepest and ...

Try this:
model2.zip

it's running also in the last dynamic analysis.
But it has serious convergence issues. I think mainly due to the plasticity in soil.
In fact, if you look at the 3rd stage (just after you activate plastic behavior, before adding the structure) you will see high accelerations ...
