I'm studying the behavior of a cylindrical tank full of fluid, for the cylinder I use elements SHELL63 and for the fluid elements FLUID80. Ansys help says:"Fluid element at a boundary should not be attached directly to structural elements but should have separate, coincident nodes that are coupled only in the direction normal to the interface."
How coupling coincident but separate nodes in the direction normal to my cylindrical tank????
 
This is easy. Make sure the nodes are rotated into the proper coordinate system, which should be the same between all nodes and if they aren't already then couple in the direction needed.

CP,NEXT,UX,ALL !couple all selected nodes in the UX direction

 
Thanks for interest Stringmaker, I have already solved using CP command. To the next one!!!!
