Hi, I would like to know if it is possible to use the Domain Reduction Method load pattern.

If is not possible, i really apprecite any sugestion about how can I apply this type of load to a 3d soil mesh.

Thanks in advance.

Thanks a lot Mr. McKenna. I guess the problem was the mesh that I use on the soil domain. First I used a very irregular hexahedral mesh, but then I changed to a mesh with degenerated tetahedral stdBrick elements and it works quite better.

The problem now is that when I use a very refined mesh (almost 40.000 nodes and 200.000 elements for the 80m x 80m x 40m sized soil domain) instead of a very coarse mesh (which works), I get segmentation fault when running the model using OpenSeesSP on carter and local machine on Neeshub (independently the number of processors). When running the model on a desktop i7 with win7, then I get:

job aborted:
rank: node: exit code [:error code]
0: PCname: -1073741819: process 0 exited without calling finalize
1: PCname: 123
2: PCname: 123
3: PCname: 123
4: PCname: 123
5: PCname: 123
6: PCname: 123
7: PCname: 123

The errors and the segmentation fault occur after one succesful analysis step of a two steps gravity analysis with transient integrator and updateMaterialStage for the soil material.

I apreciate your support.

Hi,

I'm modelling a 16 story shear wall reinforced concrete building, with mat foundation and soil for the analysis of the soil-foundation-structure interaction phenomenon. The building is modelled using bar elements, but the floor slabs and the mat is modelled with shells. The soil domain is formed with hexaedral solid elements. The model is almost full non linear and has around 2.5 million DOF´s.

When I run the gravity analysis for the whole model (I haven't tried the dynamic analysis yet) using OpenSeesSP (v.2.4.0.10) on the neeshub machines, I get this error message:

If I separate the structural model and the soil model, an then I run only the structural part, I get this message:

Using an i7 desktop machine (OpenSeesSP v.2.4.2), I get:
Error WARNING MumpsParallelSolver::solve(void)- Error -10 returned in substitution dmumps()
cause: Matrix is Singular Numericaly.

This is driving me insane. I have tried lots of things, but I can't find the solution. I really need help.

I would really appreciate your valuable help.

Thanks.

Best regards.

Do you have the solution??

I have the same problem, please post any information.

Thanks.

Hi, did you check the status of mpi?

It could be the credentials (user and password) of mpi. They must be the same as windows user account.

Regards.

Hi, it could be the version on the OpenSeesSP or OpenSeesMP executables you are using. I had the same problem, but I downloaded the latest executables (and of course properly for 32 or 64 bits) and then it worked fine.

Hi, I´m trying to download the zipped files, but it is not possible because the page doesen´t exist.

Can anyone help me please???!!!

Best regards.
