Dear all,

i am trying to export a transient velocity profile at the outlet of a pipe flow, which i want to implemet at the inlet of another LES model in ANSYS CFX.
i can export (x,y,z,u,v,w) at the outlet for every time step but i don't know how to import it in the new model for every time step.
i hope that someone can help me with this problem.

Best regards

Either
1) user fortran to read inlet velocity profiles,
or
2) If the inlet is planar (say x,y) you can replace z with a time variable instead. Create a big text file with
x1,y1,t0,u1,v1,w1
x2,y2,t0,u2,v2,w2
..... and so on.....
x1,y1,t1,u1,v1,w1
x2,y2,t1,u2,v2,w2
..... and so on.....
x1,y1,t2,u1,v1,w1
x2,y2,t2,u2,v2,w2
and then you call the profile with the arguments (x,y,t)
