JEYA Guest Posts: n/a	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
