Hi,

I got to know that for running simulation in parallel for RBF solver their need to make sure each partition has atleast one boundary point that is on the moving boundary.

By this constraint, I can easily run my simulation for 4 cores (nsubDomain 4; method simple (2 2 1). However, I want to run the simulation for more than 4 cores (such as for 8, 16, 32; I have system with 32 cores, yet).

So, to do that I have to provide atleast one boundary point of moving boundary at each partition. And I don't know how I can achieve this? Can anyone put some light on it.

Number of mesh elements: 4,00,000

Please, feel free to ask for more information. Any kind of Reply will be really helpful.
Thanks.
