iterative running of sub models
 

Hi all:

I have a huge 3D (360 deg.) fluid domain. I got strong necessity to simplify the domain by chunking it to two sub domains and also with two different sector angles and run both iteratively till I derive converged solution. To avoid huge mesh size. I got only the inlet and outlet pressures (BCs) of the overall fluid domain. The bi-sectioning of the model is planned to have it at a location where gradients are very less.

The process I would like to implement to this problem is as follows

1. Run Domain-1 separately with pressure BCs (assuming exit pressure BC). 2. Mass outflow from this run is captured and supplied as inlet boundary condition to Domain-2 3. Run Domain-2 with this mass inlet and given exit pressure BC. 4. Extract inlet static pressure from second run and supply back that pressure to the first case. 5. Keep iterating two domains till results across the interface converge.

Is it a right way to do? Is there any other existing process behind?

If this is a correct, how can I map one 3D sector results to another, when they are different?

Please let me know.

Thanks in advance Babu
