I defined my structure with a model builder of -ndm 3 -ndf 6 and my soil as -ndm 3 -ndf 3 with a stdbrick element. I connected the base of the structure with the brick elements with eqdof in dof1 and dof2. my analysis failed even for gravity load. what kind of constraints did you use to connect the base of the structure to the soil. I aslo tried to use rigid link, but it gave me an error because we cannot connect two nodes which have different dof. Michael midezutd@gmail.com

I'm trying to do an analysis considering soil. I used Gid+Opensees to visualize my model and then get the tcl code. I get the following error.

I am having the same problem, how did you solve it?

Is there any way I can model Shearwalls other than THUShell elements? Can I model elastic shear wall elements or by using fiber elements? I changed the column and beams to elastic elements but still, I got convergence errors when doing Pushover analysis or couldn't do Gravity analysis.

I modeled a 4 story 2 way assymetric reinfoced concrete model in Opensees and when analyzing for gravity load I get the above error. I modeled the shearwall using multi-layer shell element THUShell. I was using "forceBeamColumn" element for the beam and column elements with Lobatto integrator. I also tried a "nonlinearBeamColumn" element. what is your recommendation to solve this error?

when using CuSP solver I get "Function load error! The version of DLL may be incorrect." error. how can I solve it?

I came across the same error. Did you find a way to solve it?

I also came across a similar problem. Did you find any solution?

I also came across a similar problem. Did you find any solution? Does using Mac version solve the problem or you found any other way?

I am using OpenSees windows Current version 3.0.3
I modeled a 3d structure with a shear wall. I used a multi-layer shell element for the simulation of shear wall components. PSUMAT - NOT DEFINED IN THIS VERSION, SOURCE CODE RESTRICTED error is halting me . nDmaterial PlaneStressUserMaterial is used to create the multi-dimensional concrete material model.
1. Can this material or any material related to this error be used in this version or do I need to change to other versions?
2. How can I solve this error?

Hi
I'm having a problem when I run a 3-D model for gravity load. My model is a two way asymmetric 4 story structure with Shear wall modeled with ShellMITC4. It appears to give this warning when running for gravity analysis.
