Hi all,
I am trying to simulate the motion of a dolphin fluke on fluent. I am modelling the fluke with an aerofoil (NACA 0012). I have successfully complied and loaded the following UDF which should describe the shape of the foil around a thin centre line.

I am struggling to mesh a thin line as it disappears when imported to meshing software. when I draw a very thin rectangle in place of a line I can mesh around it, BUT there is no motion during mesh preview.


My UDF is attached

Is anyone creative enough to help solve this challenge?

Many thanks
