Hi users,, How can I use the results of a first run ( pressure and velocity at a specified location) as a boundry condition for another run??

Yes, ###CFX 5.6### I will try to help with a example:

First Simulation.
:>Post: *Export > Variables: X, Y, Z , pressure
:Local: Plane 1
:Save: pressure.dat

Second Simulation
:FUNCTION (cloud interpolation) : Pressure

Argument List = [m],[m],[m]

Option = [Pa]

(open the file: pressure.dat)

### if you want change something ###

*Expression > new(pressure_S1)


*In the Boundary Conditions, change value to Expression and use pressure_S1

To use velocity is necessary: velocity u, v and w (one by one).
