transient flow
 

Hi,

I would like to model a transient flow, where at each time step I specify a new inlet boundary condition and the solver carries on its calculation from the last time step with this new boundary condition. Has anyone had any experience with this sort of problem? Any advise would be very much appreciated.

The transient flow condition can be modelled using the bcdtrn.f file available in the user3D directory in the TASCFLOW. You need to specify the value of the different variable like the U, V, W velocities or mass flow or the pressure as a function of time (Simulation time, STIME) at the particular boundary. Further help is also available there in the User source code documentation. Hope this will do your job regards sudar

CFX-5, CFX-4, or CFX-TASCflow?
