Hi,

I am intending to decompose a large scale (cm size) domain into 5 portion but I want one of the portions to be further divided(decomposed) into another 5 part.
I am pretty sure none of the common decomposition methods(metis, scotch, simple, hierarchical) is able to do it as they do it arbitrary based on the weight of the cells at the beginning.
The reason I'm doing this is I am investigation the behavior of MicroFluidics at specific part of my domain which usually falls into one portion of the decomposed domain and this portion has to carry most of the computation. I guess using manual decomposition I should be able to specify where and how the domain to be decomposed. Does anybody have any clue how to handle this?

Thanks
