Hello

I am recently working with starccm+ and I am currently trying to impose a unsteady velocity profile inlet. Since the formula for my case is quite complex to use a field function I decided on trying the table(x,y,z,time) with cylindrical coordinates. However it seems that the simulation is not updating the value.
Just to give an example my table is somewhat like this:

r theta z Velocity [t=0.01s] Velocity [t=0.02s] ....
0 3.14 0 0.01 0.005

So what I presumed was that the first three columns where for the coordinates and then all the others were for the velocity speed for the given point. Now I have read previous posts and maybe I need a field function to interpolate the table but since I didn't read anything like that on the documentation I would like to ask you guys for guidance.

Sorry for the long post and thanks for reading.
