Re: Not converge
You meshed your slab to apply a floor load, but the slab has no element property assigned. So the analysis is saying that the model is singular. Regarding your first model: Use a finer mesh (a shear wall cannot be analyzed with just 1 element) For the slabs, due to the non-structured geometry, use a...

Re: Analysis did not converge
Double-check your beam elements. There's something wrong: In the section aggregator for beams, you used the concrete material for Vy and Vz... are you sure? You should use a proper shearforce-sheardeformation, not a compression-only stress-strain law... as you did for the columns. Then you defined h...

Re: The non-convergence of gravity analysis in two-dimensional tunnel modelis
the top layer of soil is detached from the other one. It is falling down.
Select the 2 soil layer, merge them using the SewFaces command, and re-mesh. The analysis should run after that

Re: Using Pinching4 but the result is strange
You should use it in a section aggregator to represent the shear behaviour of the shear wall, while the fiber section should represent the bending behavior. You should have a look at our beginner webinars. The last one explains this: https://asdea.eu/software/get-started-webinars/ 3D Frame Structure...

Re: mesh problem
There's a problem with the interaction you used for the beam-solid-coupling. The master should be the beam-end-node (pile-top node) The slave should be the face of the cap solid However, since your cap is made of a single cube, there is only one face at the bottom. Doing this, the beam-solid-couplin...

Re: Viscous-elastic artificial boundary Definition
That's the reason why we implemented the automation ASDAbsorbing boundary. The theory says that the dashpot should be used just to absorb outgoing waves, so it refers only to the soil. On the other end, the stress of the free field should be transferred to the soil (and not vice-versa). If you read ...

Re: Coupled RC Core Wall with MVLEM-3D
I am aware of the custom commands, but do you have an example for this (I think I have seen a video, but cant remember which one)? Where do I add this in the analysis que? I know how to write these in OpenSees, but I am not sure what part of OpenSees code needs to be included in STKO. Regarding thi...

Re: Coupled RC Core Wall with MVLEM-3D
It was a small bug we already fixed for the next version. Here are the updated files: MVLEM_SFI_MVLEM_3D.zip Replace the original ones in: C:\Program Files\STKO\external_solvers\opensees\element_properties\beam_column_elements Don't worry because that small bug was only affecting the automatic resiz...

Re: Add new features
You can use the Python API for that.
Here's a script that does that. It is well-commented so you can go through the code to see what it does.

Re: Using Pinching4 but the result is strange
It's not about the unit... The uniaxial material in OpenSees can be used for multiple purposes. Depending on what physical behavior you want to represent. If you put it inside a fiber section, then it should be a stress-strain curve, not a force-displacement. Could you please explain what your pinch...
