Leaving solid part without mesh?
 
1 Attachment(s)
Hello I have a fluid pass over solid thin wall with known thickness. I need just mesh the fluid region as shown in picture? is that possible in meshing program? if possible how i can do it?

You need to create geometry for fluid region and mesh it. Isn't it obvious?

I think you not understand me. Actually I want draw two volumes one for solid and other for water I just want mesh fluid part and leave solid part without mesh (see last pict)? How i can do that?

Supress unwanted part

I attempt suppress the solid part then create mesh for fluid part only but the problem in Fluent just the fluid part appear? i want both parts appear in fluent? how to do that?

For what? Fluent, CFX and other codes operate with mesh, but not geometry.

Actually the picture i sent exist in ANSYS FLUENT 13 help files exactly in fluent_13.0_lecture07-heat-transfer file please refer page 8 & 9 to check this issue?? how they mentioned that its possible to leave solid part without mesh in Help files if not applicable in FLUENT?

You didn't understand. Solid region is not geometrically modelled and not meshed in that case. You specify wall material and thickness. Solver solves 1D Fourier's Law for heat transfer in normal direction.

You mean wall boundary not material because you mention solid will not be modeled just fluid region will drawn?

Edit properties of fluid domain boundaries (walls) and you'll see material and thickness settings there.
