CFX4: Free surface grid movement algorithm
 
Hi Guys,

CFX4: Free surface grid movement algorithm

I have tried to model "Free surface grid movement" of the channel using CFX where the free surface is set-up to be a wall with zero shear stress, and the algorithm then moves the grid points on the surface until the physical pressure is constant. I have followed the CFX instruction however I got following error message. Could any one know what is that meaning …

VERTEX NUMBER 10666 IS NOT VERTICALLY BELOW A SURFACE VERTEX

Is there any equivalent of Free surface grid movement algorithm in CFX 11.

Thanks Regards Jeya
