Thanks for the information

Hi all, I am working to develop a neural network material in OpenSees. As a first step I want to implement an elastic model for 3D analysis. I know that this model has been fully implemented; however, I want to be sure I am able to implement the simplest model in OpenSees and then work in the more c...

Thanks Frank for your answer I tried to use: system Mumps -ICNTL14 50 and I obtained the following results: WARNING MumpsParallelSolver::solve (void)- Error -9 returned in substitution dumps() WARNING ModifiedNewton::solveCurrentStep()-the LinearSysOfEqn failed in solve() DirectIntegrationAnalysis::...

I tried and it is not working (Error -9) it seems something is missing, thanks for the reply

I am trying to run a code developed in OpenSees in OpenSeesSP, as you told us in the workshop we need to change the system (in my case system SparseSPD) to Mumps. Reading the manual it says that due to copyright restrictions we have to install the system solver, I look in internet and the webpage wh...

I am using UCSD soil model and elements to model soil liquefaction. I need to verify the stress-strain relationship of the material, but, the recorder Element command is not working, therefore, I am not able to obtain as an output neither the stress nor the strain time histories. I already have the ...
