Re: Convergence Issue with Force Beam Element
First I suggest you use more reliable materials. Your concrete has some strange behavior (use the material tester and check it): CFail.png Also, your steel seems buggy, it does not provide any stress SFail.png Try something simpler like Concrete02 and Steel01 (or Steel02). Then you may improve the c...

Re: Convergence Error in SFI-MVLEM Model
You are modeling in N-mm: Try a higher reference horizontal load (for example 1.0e6) Now you have 1 N of reference load, so the load-multiplier (which is an unknown in the Displacement-Control) is very far from the solution. It's better to assign a reference load which is closer to the expected (so ...

Re: Retrieve stresses on GaussPoint
It's because the PIMY material gives you a 7-components stress vector (the first 6 are stress components, the last one is an internal variable). Therefore this line is not working as the result has a different name (7 instead of 6). Change this string stress = db.getElementalResult('stress (Volumes;...

Re: Convergence Error in SFI-MVLEM Model
Just change the constraint handler from Transformation to Penalty. Now you have SP (imposed displacements) at the same place where you have MP constraints (EqualDOFs). This can give problems to the Transformation method. In cases where the SP and/or MP constraints overlap, just go with the penalty. ...

Re: Adding simple soil springs
1) Should the duplicated faces be at the same location (overlapping) with the basement walls, or shoul there be any distance in between? If there should be a distance, what should it be? You can do whatever you want. A zero-length does not consider the distance between the nodes. But if you keep a ...

Re: Coupled shear walls with diagonal reinforcement
There are some mistakes in your model. Let's try to fix them one by one. You have several floating vertices (for example geometry 125, 126, etc...). They are not attached to anything so they will generate a singular stiffness matrix. Probably they come from your CAD drawing, but if a geometry will n...

Re: Analysis using ASDAbsorbingBoundary3D
Hello, here is a follow up information. I have noticed that when I remove the soil on the sides of the basement walls, but keep the soil beneath the building, the drifts in the SSI model increase drastically (see below). I find this interesting, but I am having a hard time understanding why is this...
