wanghaojie Member HJ Join Date: Nov 2011 Posts: 30 Rep Power: 14	Hi all, I want to save velocity on a line for every timestep. But it seems udf cannot do that because line has no ID as surfaces. I want to study the cross-spectrum of the velocity on the line, so can anyone enlighten me how this can work? Many thanks
