Hello everyone, I did URANS simulations in ANSYS CFX, and I need to extract the data of "u" and "v" velocities for every 10-time step. I have the code for extracting data for every time step. Does anyone know how to do this simple task? Thanks in advance.

# Session file started:  2023/03/11 07:34:35

# To avoid unnecessary file pre-processing and modifications, include
# COMMAND FILE at the top of your session file.
# If it is not included, the file is assumed to be older and will be
# modified for backward compatibility.
COMMAND FILE:
  CFX Post Version = 20.2
END

! @steplist = (5000...7000);

! foreach $curstep (@steplist) {
> load timestep=$curstep

Here's an example CFD-Post session file for exporting every 10th transient file:

!$fileout="My_Export";

!$bcname="out";

!$numsteps = 50;

!$interval = 10;

 

COMMAND FILE:

  CFX Post Version = 19.3

END

 

#!for ($j=0; $j <= $numsteps; $j++) {

!for ($j=0; $j <= $numsteps; $j += $interval) {

DATA READER:

  Current Timestep = $j

END

> load

 

! $filename = "$fileout" .$j.".csv";

EXPORT:

  Export File = .\$filename

  Location List = $bcname

  Variable List = Velocity u, Velocity v, Velocity w

END

>  export

Thank you for your help.
