Dear all,

I have a problem when I want to run my model with ASDConcrete3D physical property. I get an error that the nDMaterial cannot be created (see figure). It is possible to run the model with an elastic isotropic nD material, so I think it is not a problem of the geometry. I also tried running the "mestyanek_shear_wall_coarse_implex" model from webinar #32 and got the same kind of error. Is there a parameter that I have wrongly assigned or is there something missing that causes this error?

Thank you for your help.

Kind regards,
Mats

Hi, you should use the recent version of OpenSees (your screenshot shows an older version. v3.4). I use version 3.5.1, I do not face such issue. You can check with the link below for a precompiled OpenSees version or the official OpenSees site.

Dear Prabakaran Kesavan,

Thank you fro your help.

Version 3.6.0. from the OpenSees website doesn't include the solvers. Where can I find them? The link to the compiled version only includes the 3.4.0. solvers.

Kind regards,
Mats

Hi, I downloaded the OpenSees solvers from Prof. Nicola Tarque's researchgate website. Though it mentions version 3.4.0 in the site, I could see version 3.5.1 when I actually installed it on my computer. So, you can try it.

Hi,

I just tried uninstalling the previous and installing the one you said but I keep on getting version 3.4.0. when I run an STKO analysis

Are there any other things I can try?

Kind regards,
Mats

Ok, I understand that. You need to write to Dr. Tarque. Alternatively, you can compile the OpenSees source code and use it with STKO. Following YouTube videos can be helpful in order to compile the source code.
