Re: Error using OpenSeesSP

Okay, I seemed to have found the source of my own problem. I'll write it down here just for the records. In my model I had some SHELLMITC4 elements and they inherited LayeredShell sections. Apparently, Mumps doesn't like it. Soon as I switched to ElasticMembranePlateSection, things went back to norm...

Re: Error using OpenSeesSP

I am encountering the the exact same problem. I have two different models. One of them runs fine on all threads but the other one can only run on one core?

Does anybody have an idea what might be causing such error?

Ömer.

That is exactly what I did, many thanks Frank for the clarification! fmk wrote: > the numbering of the dof does not effect the answer (at least if numerical > roundoff is not an issue) .. the error you see from the force beam column > is coming from the formulation, it is force based and not displac...

Re: Considering shear lag effects in T-shaped non-planar RC

You cannot capture such phenomenon using beam-column elements. You can read the works of D. E. Lehman, L. N. Lowes and J. Pugh on modelling these shear wall elements. The only option that I am aware that you can consider is to use shell elements. There is this multi-layered shell element (MITC4) dev...

Issue with the force-based element

Dear forum, I would like ask a quick question about a particular error that the force-based element spits. The error message is "ForceBeamColumn3d::update() -- could not invert flexibility\n". You might be familiar with this too. This means that it cannot obtain the element stiffness matri...

Re: Analysis of a 3D Tall RC Building with Core Walls

Thank you very much for the prompt reply! I had the same doubt for a long while untill I ran the same analysis using only the core-wall configuration where the same elements still exist. And it runs just fine. I am wondering if it's the diaphragm causing problems together with the gravity beams acro...

Analysis of a 3D Tall RC Building with Core Walls

Hello all, I wish to consult with you expert Opensees users about a particular problem I have. I am first putting up a general description of my model and then I will explain the type of problem I am encountering. Finally, I will share some observations that might trigger a light-bulb moment for the...

Analyis using CUSP solver

I am aware that this topic was posted a couple times in the past but I could not find any clarification/solution to this issue. I am trying to use CUSP solver after following the steps explained in OpenSees wiki page. However the only different action that I took was that I installed CUDA v9 instead...
