Could anyone please tell me if it is possible to run OpenSeesSP in Vista 64-bit plattform, by installing the MPICH2 version for 64-bit? I would like to take advantage of 8 processors in a 64-bit system. I tried downloading the binary from www.mcs.anl.gov, corresponding to Win64 EM64T/AMD6, but it se...

I changed the system from Mumps to UmfPack, thinking that my initial problem was the parallel interpreter, so I ran it in the sequential OpenSees.exe. I got similar error messages with the sequential interpreter as well, so now I believe my problem is in the actual solving of each element. By the wa...

Hi Frank, I'm going to email you the file of the script I'm using right now. I am using Brick 20N _u_p_U elements and nDMaterial NewTemplate3Dep material model. This is the error message I recently got: WARNING MumpsParallelSolver::solve(void)- Error -10 returned in substitution dmumps() WARNING Kry...

Frank, I am running into some inconsistencies in the results (stress calculations) after trying modelling a looser soil layer on top of a denser one. I believe there might be a bug in the code. I am still running with 1 processor, eventhough the commands are setup for parallel computing. This was wo...

This is what I am using for my material, followed by the elements definition: #~~~~~ Material Parameters ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 set MatCons "$rho $e0 $G0 $poisson $P_at $k_c $M_csl $c $lambda_c $xi...

Frank, I did download the binary again and tried to run my model, obtaining the following NEW error log in the DOS shell: C:\>mpiexec -np 2 OpenSeesSP.exe C:\model.tcl END of Stage 0: SOIL COLUMN CREATED ---------------- Stage 1 begins: CREATE SELF WEIGHT ---------------- Slave Process Running 1 FEM...

I appreciate it Frank. Does it mean I have to download a newer version of the binary and try it again?

I am using nDMaterial NewTemplate3Dep (from UCDavis). Please let me know if I should change something.

Thank you.

To be more precise, my processor is an AMD Turion™ 64 X2 Dual-Core.

Hello, I have installed and configured all the files so I can make use of OpenSeesSP. I followed very carefully all the steps in doing this. Whenever I try to run (for instance): mpiexec -np 2 OpenSeesSP.exe C:\model.tcl I get the following error text: Slave Process Running 1 FEM_ObjectBrokerAllClas...

No, I already tried and it just keeps the initial settings (first constraints).

Silvia,

Thank you for your reply. How can I change my contraints (fixed DOFs) within the same modelbuilder?

Maria

How about simple constraints? Does "remove" command work to distroy constraints imposed in a previous analysis?

Hello, Is there a command to link the DOF of u (solid displacement) and U (fluid displacement) in one node of a Brick8N_u_p_U element? Does someone have a reference to find this command in Opensees? I would appreciate any comment. Thank you, MARIA JAIME Doctoral Student Dept. of Civil and Environm. ...

Thank you rjaeger! I had Prof. Jeremic's notes, however, it doesn't have any specification about the modeling in Opensees of a constant confining stress while axially shearing an undrained saturated soil sample. Right now I use Brick8N_u_p_U elements and I've been running my model without such confi...
