fluid-solid zones meshing help
Hello ,
I'm working on a problem where I have a flow through an annulus, with the outer surface being heated by a uniform heat flux. For this purpose , I propose to model the inner surface as a fluid and the outer surface as a solid. My question is - How do I get these different regions ( fluid and solid ) to talk to each other once I mesh them. I read online that the fluid and solid are meshed independently in ansys workbench. Any help would be appreciated. Thank you |
Just a boco
If you want conformal mesh...
In DM or your CAD tool you need to create a multi-body part. You can do this by right clicking on the top of the parts branch of the tree... However, if your heat come from a mechanical simulation or what ever, you can interpolate the heat very easily in WB. The advantage of interpolation is that your FEA mesh can be coarser than your CFD mesh. But in the end, you just want a uniform heat flux into the flow region... You don't need a solid region at all. Just make sure that your walls are in a unique named selection (so you can select it easily for the boco) and then apply the heat flux as a boundary condition in the CFD solver. |
Thanks a lot.

Question ???
Hello,
Anybody have some example from: How do I get these different regions ( fluid and solid ) to talk to each other once I mesh them. I read online that the fluid and solid are meshed independently in ansys workbench. Any help would be appreciated. Thank yoy |
You need to highlight the parts in DM (use CTRL to select more than one) and then right click to "form new part".
This will produce a multibody part, which means it is an assembly of separate bodies, but it is all meshed conformally. |
