Dear STKO team:
I used STKO to simulate the nonlinear dynamic characteristics of soil and tunnels, the software is very useful, but I have encountered some problems when using it, please help me check the model , the following is my model, it works normally.
1. I can't easily observe the fiber ...

Thank you for your reply, but I noticed that there was still a gap , and including the stretching behavior

thanks for the reply, I have one more question, which is about the place where the soil and the structure are in contact with each other, in fact it is compressed and not tensioned, my model uses zeroLengthContactASDimplex, but after running it it is found that there is a relative displacement ...

Thank you for taking the time to reply to me! I would like to construct a three-dimensional seismic tunnel-soil model. Is it appropriate for me to only establish the FF columns on both sides? Do you have any better methods or suggestions for the model? I watched the SSI webinar and noticed that the ...

Dear STKO team：
Hello, I have reviewed the ASDAboundary3D material and have applied them in the three-dimensional analysis of the tunnel and soil. However, I am unsure if this application is correct. Could you please take a look? Below are the model attachments.

Forgot one important thing: do I need to add a factor when entering seismic waves? In other words, if I enter a ground motion peak of 0.3g, it is not as long as it is consistent with the peak value displayed in the function plot in the timeseries.

Hello, STKO team：
I have questions, if the model built with FF and LK is the model I built correct or the deformation is too large so that I can't find out where is the erorr?
By the way, If we use ASDAbsorbingBoundary , is it possible to analyze the soil model with FluidSolidPorousMaterial?
I can ...

would you mind to recommend me a related link? Learning videos or examples on adding ground motion, adding a uniform excitation mode, and ASDAbsorbingBoundary？

Dear STKO Team,
Hello, I still have a few questions:
1. Is my unit N, mm, and the b3 coefficient of element -9.8? Or is it -9800?
2. If I want to change to KN, m, what do I need to do in the units in ASD concrete3D material?
3. If I want to apply ground motion to the soil, use the addition of ...

It's amazing, thank you.
