Default Boundary Condition When using FVM?
Posts: n/a
Hi, everyone:

How to discretize the boundary condition d(phi)/dx=0 at the right side of a 1D problem using FVM? Assuming hyperbolic system and subsonic flow.

U will find about boundary conditions in the book of Malalasekera.... or in the Ferziger one... They r very simple to read...

Good luck...

If the flux contains d(phi)/dx then use the boundary condition to calculate the flux. Otherwise use d(phi)/dx=0 to get phi at the right boundary and use it to compute the flux at that boundary.
