Re: WARNING BandGenLinLapackSolver::solve() -LAPACK routine

Dear Friends
I have once faced a similar issue with my model. I found the issue was due to improper handling of Restrained and Constrained DOFs in defining in equalDOF command though there may be other causes also. When I correctly defined them, the issue was fixed and OpenSees showed correct periods.

Job aborted in OpenSeesMP

Dear Friends My PC has 2 sockets and 4 cores (8 logical processors). I do parametric analysis (100 records) using OpenSeesMP. When I use -np as 2 or 4, the program runs fine. But for -np value 8, it runs for about half of the records (50) and then I get 'job aborted' error from anyone processor. I k...

Warning No Numberer type exists

Dear Community I am new to parallel processing. So, I wanted to learn it. I installed all the requirements as per Dr. FMK's instructions. Then, I executed the ex4.tcl in my OpenSeesSP console. It threw an error saying that "Warning: No numberer type exists (Plain, RCM only)". Can anyone help me to u...

Re: Extract Results

Dear Friend You can record the desired result quantity (forces/displacements etc.,) in either. txt or .Out or . dat files using 'recorder' command. Once you have got the files, using MATLAB ' load ' and 'plot' command , you can plot whatever graphs you are interested in. You can even see an example ...

Re: lumped plasticity model & pushover

Dear Friend What uniaxialmaterial model did you use for retrofitted structure? It seems from your post that the retrofit model behaves something like elasto-plastic with strain hardening type. So, you may avoid convergence problem if you model that behaviour as Steel02 uniaxialMaterial as per OpenSe...

Re: lumped plasticity model & pushover

Dear Sualim I assume that the hysteretic loop that you mentioned means the backbone curve for the pushover curve. A hysteretic loop is required only during the cyclic analysis. The backbone curve in your case is multilinear, so there is a possibility of getting convergence error in such cases. The q...
