hi all see below trying to simulate a gear pump with two gears in a housing with inlet and outlet.

i know that i may have to use cellZones but not sure how to do that. also something about using setSet i have read to do this but its still not clear to me....

ok so I decided to use 2 mrfs and a fluid domain, I have nearly running code:
