constant and exotic source terms in NS eq
 

Hi, I'm simulating with Fluent the development of a flow initially at rest under EM forces.

I wrote an UDF which calculates the distribution of EM forces. However, this distribution is constant (neither time nor flow dependancy).

So, I'd like to find a way to prevent Fluent from calculating at each iterations the distribution of forces. It seems to be impossible to use a profile, and the function "UDF update interval" doesn't seem to work correctly.

Thanks for ideas or solutions...

Please post ur UDF

Thanks, but i found a solution with the utilisation of UDM (User Defined Memory).

Cordially.
