boundary type specifications

Agovale46 · September 10, 2009, 05:47

hello to everybody.
I have water that flows over a solid body. The water 's volume and the solid' volume are not connected each other, thereby in the boundary among the two volumes ,there are 2 overlap surfaces, meshed in 2 different way. the question is: when i do the boundary type specifications, i have to do it only for one surface in the interface, or i have to do it for both? and what kind of the specification type do i have to put over the two surfaces ( there's the concenction phenomena ,obviously)?

*except if you want to compute conduction, you don't need the solid volume.
So you can delete it. Your computation's model will be simply the fluid domain with a hole (solid volume substracted)

*if you solve also conduction, I never used this feature, but I would try to connect the 2 volumes, and define the solid one as solid
check help, because I am not familiar with solid conduction
