Boundary conditions and dimensions on voxelized domain
March 16, 2018 07:31PM
Hi all,

I'm having trouble imposing boundary conditions on a voxelized domain similar to the aneurysm example. In that example a velocity inlet boundary condition is used, while in the other two outlets, a constant pressure Neumann boundary condition is imposed.

I am trying to make something similar, but with a constant pressure Neumann boundary condition on the inlet and a time dependant Neumann boundary condition on the outlet, so that the flow oscillates.

Also, I'm having trouble on the geometry importing step. I can't seem to find a way to make the domain fit to the size of my drawing. Also like in the aneurysm case, where the domain envelops the 3D mesh almost perfectly. When I thy to follow a similar procedure, my domain doesn't match the size of my drawing.

Thank you all.
