Re: remove mp command issue
i did not built it myself.I am using latest version of openseesSP.exe dowloaded from the website. and i am using my personal computer.

remove mp command issue
I am trying to remove equalDOF from the system i have but having the following error.
ShadowSubdomain::removeMP_Constraints() - not yet implemented.
I am using openseesSP. Is it possible to remove equalDOF ?
Thanks,
Ozgun

Re: problem with Manzari-Dafalias material
mhm,
I think it is not a suggested value. 0.05 is used in the generic examples but you should use the Poisson's ratio that is valid for the problem you are working on. otherwise your gravity analysis does not end up with correct initial state of stress.

Re: problem with Manzari-Dafalias material
can you try to play with alpha parameter and see if it works?

Re: UpdateMaterialStage in OpenSeesSP
hi brag006, Can you briefly explain the way you achieved to solve the problem you stated here? I am running site response analysis. Depending on the size of the problem, I am having the warning "WARNING: MaterialStageParameter::setDomain() - no effect with material tag 1". An this warning ...

OpenSeesSP potential parallel computing problem
Hi, I am using Manzari-Dafalias model with parallel processor. I have a very simple 1 column of soil on which I am doing gravity loading and dynamic time history analysis and it works in sequential computing without any problem. When I run it in parallel computing using SuperLU solver, I am getting ...

Re: Dafalias Manzari constitutive model in OpenSeesSP
Dear all, I would like to ask if anybody used Dafalias-Manzari model with mumps solver. I am trying to use it and having issues about the speed and convergence. I am linking another topic in order not to duplicate the issue. http://opensees.berkeley.edu/community/viewtopic.php?f=7&t=61851&p=...

Re: Mumps Solver Problem
fmk, thanks for your reply. based on your suggestion, i have tried couple of different solvers with different time steps for gravity analysis. in some of trials i have kept both elastic and plastic stage for gravity analysis and for the others i have removed the plastic analysis just to be able to s...

Mumps Solver Problem
Dear all, I am using OpenSeesSP to take the advantage of parallel computing. I am using Mumps solver in my analyses. In my previous work, I have successfully run 3D simulations using brickUP elements with PressDependMultiYield model. Now I switched to Dafalias-Manzari model with SSPbrickUP element. ...
