Hello,
I started using the MPI version of Mars to save time for the simulations and I encountered some problems.
The manual says that to work, the subdivision of the domain can't cross a master-slave connection. Since in my model (similarly to a cylinder compression test) the top and bottom surfaces have a master-slave connection with something else, I tried to use also the:
MpiDomainList {
RecursiveBisection ttL-PRTC Z-direction
}
I compared the results of the OMP, MPI and MPI Zdirection and they gave me three different results.
I created a word document where I explain everything in detail with some pictures.
At the end of the document I ask this two questions:
A- Is it possible to subdivide the domain in 4 parts or in the number of nodes that you required?
B- Does just the master-slave interaction create problems with MPI or also the rebar interaction?
Can you please help me defining the domain subdivision in such a way that the OMP and MPI (or MPI Zdirection) give the same results?
Thank you, best regards
