Re: OpenSeesSP and SSPbrick element

I checked my model again and found that the problem is related with TwoNodeLink elements and when I use TwoNodeLink elements, the following error will appear: "FEM_ObjectBrokerAllClasses::getNewElement - - no Element type exists for class tag 86 Fatal error in MPI_Recv: Message truncated, error stac...

Re: OpenSeesSP and SSPbrick element

when I run in SP, the model is built successfully but at the beginning of the analyze stage, some times it just freezes and some times it aborts with this error: "job aborted: rank: node: exit code [:error message] 0:Hadi-PC: -1073740940: process 0 exited without calling finalize 1:Hadi-PC: 123 2:Ha...

Re: OpenSeesSP and SSPbrick element

I create my model with SSPbrick elements and it runs well in OpenSeesMP but I can not run it in OpenSeesSP (v.2.4.10). I want to run my model using any number of processors and configuring my huge models to be run in OpenSeesMP is really difficult, so I want to shift to OpenSeesSP . Do you have any ...

Re: Rayleigh Damping Coefficients in OpenSees and SAP2000

@mhscott: the material is linear and I used both mass and stiffness proportional damping in OpenSees, but it gives different results with the same coefficients in SAP. @fmk: the connectivity, element, material properties and every thing are exactly the same but as I said, it gives different results ...

Rayleigh Damping Coefficients in OpenSees and SAP2000

Hi every body; I modeled a SDOF system with a massless column and a lumped mass at top of that. I used Rayleigh damping coefficients in order to model a 5% damping ratio. I created the same model in SAP2000 and used the same damping Coefficients but after transient analysis, the results are differen...

OpenSees Freezes at last two steps of transient analysis

I have a model and 10 earthquake records. When I want to perform transient analysis with four records of these 10 records, OpenSees freezes at last two steps of the analysis and does nothing till I close the executing window. As I said, I have no problem with other records and the problem is shown i...

Re: Nonlinear elastic material

Dear Shiva, It seems you work on similar projects as mine. It would be very useful if we can handle our experiences to each other. About your question I should say that based on my knowledge about soil behavior and soil constitutive models implemented in OpenSees, there is no no-linear elastic soil ...

Re: Error message in OpenSeesMP

So what should I do if for example I have nodes 100 and 101 in two processors and I want to tie them together?
I should tie them in just one of these two processors and they will tie together in both two processors?!

Re: Error message in OpenSeesMP

Frank, I run it sequentially and it worked well. I have some MPConstraints (equalDOF) in my model. when I deactive this constraints every thing is well but when I activate those, the error will appear. I used Penalty method to impose constraints and there is no problem with the sequential OpenSees b...

Error message in OpenSeesMP

When I run my model in OpenseesMP it prints the following error:
parallelMumpeSolver:: Error -9 returned in substitution dmumps

what is the cause of this error?

Re: convergence problem with UCSD soil models

Hi Deepak, I use PDMY material and SSPbrick element. My model is really huge and I can not post it. I have another problem with gravity step. I do gravity analysis in two steps. there is no problem with the elastic stage. When I update the material to consider the plastic behavior of soil, it conver...

Re: Remove in OpenSeesMP

Is it the same for update material stage command?
What is the rule of the DomainChange Command?

Re: convergence problem with UCSD soil models

thanks Deepak.
I fixed the gravity step but now I have difficulties with the transient step of analysis. It does not converge and I'm really tired working on it. Do you have any advice for me?
