OpenSeesSP and SSPbrick element

Post by hadisayadpour »

Hi,
Does SSPbrick element work with OpenSeesSP?

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 suggestion?
Regards

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:Hadi-PC: 123
3:Hadi-PC: 123"
By the way, if I just change the element type to bbarBrick, the model will run and no problem happens.
Thanks.

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 stack:
....
...
.."
and one other thing, I should perform the analysis in two stages. the first stage is geostatic (impose gravity) and the second stage is transient and I used MultipleSupport pattern in order to imposing earthquake displacement record to the base. but after geostatic step, an error is appear that says there is no node to impose the motion to. if I define some of the nodes again after geostatic step, it works but I don't know what is happening to my model and where is the missing nodes. after this error I'm not sure what parts of my model are missing and what parts are not.
How can I fix it?

the object broker classes needed updating to include the TwoNodeLink .. i have made changes to the source code .. i will need to test and then update the .exe .. i have asked the author for an example (if you have a small one you could send it might dpees up the process).
