Hi,

I'd like to ask if anyone know how can i read txt file with values (for example wind velocity on an inlet) and apply this value on a bc (inlet for example) on each step of a transient simulation.

What i need to do is to simulate a ventilated facade for one day with different inlet velocities on every time step

thanks
Kordou

Put the values into a 1D interpolation function and use the output of that function to control the boundary condition.

Have a look into the manual: there is a way to export profiles from post. These profiles can be used in CFX-Pre as boundaries.

Export a dummy profile from post. The file is readable with editor. Just overwrite with your values in the same format.

But this should be done every time step as the input velocity is changing with time.

I am not sure what the previous two posts are talking about, that does not seem relevant to the question.

If the 1D interpolation function is not suitable but you still want to read from a file then you will need to use a fortran user routine.
