Hi guys,
I am coding a finite volume code to calculate the unsteady pressure for a moving airfoil. I used Roe scheme, and I am really confused with the moving mesh method. I calculate the mesh moving velocity and it is really small ( ![]() As I understand, for Roe scheme, the cell surface flux for moving mesh is nearly the same as for stationary mesh, the only different is that the velocity V in eigenvalue for moving mesh is replaced by ![]() ![]() ![]() Can you guys who had the experience in moving mesh help me? Thanks! |

from a physics stand point, it makes sense that if the boundary moves slowly relative to the flow velocity it will be insignificant ( unless there's some special case). This is true until the geometry changes enough to impact the flow.
It might be considered quasi-static. |
