I have a problem with an inlet and outlet and fans between. I solved the case for a condition of fans.

Now, i want to find solutions for different conditions of fans. I just discovered that it seems better to start iterating without initializing after setting the new conditions. It converges faster. I noticed that the residuals react to the change in B.C.'s. This means (i think), my new b.c's are recognized by fluent even if i do not make an initialization.

Is this method correct? Do you know something about it? Do i need initialization to make any new b.c.'s accepted?
