Any 3D tutorial for fluid dynamics?

Hello,

I am a new user for the FEATool and cannot find any 3D tutorial for fluid dynamics, except for many 2D examples. Can anyone provide me one because, for example, I try to build a mesh inside a box but the model gives me the mesh only on the surfaces of the box but not inside the box?

Thanks.

John

3D modeling works just as 2D but takes longer to solve due to larger and more interconnected meshes. You also can find many 3D fluid flow Matlab m-script file examples here (ex_navierstokes#.m models):
