how can i get valid variable names in fluent profile
 
I want to use a profile to descript the stroke of the movewall in dynamic mesh, i have several experiment point datas(displacement of movewall vs time).My question is, how can I descript the displacement in x direction with variable(like v_x for velocity in x direction). Need your help.Tks!

Hi,
if you use DEFINE_GRID_MOTION macro, you have to provide dx every time step so, you can use v_x as dx/dt and that's all.
