How can I define the number of skip in path-line using text command?

I am trying to save the path-line at every timestep.

e.g Solve > monitors > command display path-line velocity-magnitude 3 5, 180

I've managed to define sufaces(3 and 5) and velocity range(0 ~ 180) but not sure how to define the skip number using text command.

Any input would be appreciated.

Thanks sam

well, just find out that 5 is the skip number, then I need to know how to select more than one surface. thanks

Hello! Try the command which will ask Fluent to write each timestep. That should work. Good luck.
