Boundary condition function
 
Hey,

is it possible to define a boundary condition functions in fluent. I would like to vary my mass flow rate untill my defined force on a special part of the figure because of the fluid is reached. It should be something like this:

if the force is to high then raise the mass flow rate, if the force is to small then reduce the mass flow rate until the force is exatcly reached.

If somenone knows a way to do this in Fluent or at the Workbench please let me know.

Thank you!

I can tell you it is possible by using a UDF (user defined function) for the boundary condition values. You might want to check out the UDF subforum on how to use UDF's.
