Default "interior" boundary condition-urgent
Posts: n/a

I have a circular hole on the surface of a cylinder and when I read the mesh file into FLUENT, it changes the "interior" boundary condition specified by me on the circular hole to "wall" with an error message : 'cannot change "face#" to interior because there is only one adjacent cell thread'. But this circular hole cannot be wall.

Anybody have any idea what is wrong?

Thanks, Shankar.

Hi shankar,

'interior' surface is specified when we have fluid on either side....if i have understood your case correctly, the error message appears bcoz you have fluid (mesh)on only one side of the, in the mesher just define this as a separate surface. let's say 'hole' the mesh into fluent and define whatever bc you have for the hole...

bye, ashish
