Solving in two Fluent windows
 

Hi. I want to solve independently two zones(A,B) which exchange interface boundary data. Do you have any idea to solve alternatively & automatically as the following?

1. In a Fluent window, solve zone A and write a interface boundary data profile. 2. In other Fluent window, solve zone B with interface boundary data profile from step 1 and write a new interface boundary data profile. 3. Repeat step 1&2.

This problem, of course, can be solved in a Fluent window by scheme language. However, in this method, we must read and write cas&dat file, repeatedly. So, it needs much time for reading and writing. Please, give me good idea or comment! Thanks in advance.
