I need to model a sail as part of my dissertation, and have been told that with v5.6 it is possible to make a thin surface/membrane. Ive spent hours trying to work out how this is done, but to no avail....can anyone help me out? It only needs to be 2-D as I am only looking at a small section, but it does need to be attached to a cylinder(the mast!)

Thanks a lot

Hi Dave,

What preprocessor are you using?

Glenn

in CFX-Pre under the Edit boundary window using Wall type boundary you are able to mark 'Create thin surface partner' option. this way pre defines it as a thin surf. But I think you are supposed to create 2 bodies/3Dregions with your geo/mesh generator which will form the fluid/flow domain (defined in pre also)
