Hi,

I have a question regarding non-uniform FVM staggered Cartesian grid.

When the grid is non-uniform, I believe there are 2 ways to discretize the volume of the u/v grid, assuming the p grid is created.

1. The east/west faces of the u grid intersects the cell center of p. In that case, the distance of the east/west faces from the cell center of u will be different. the volume of u and p cells are different.

2. The west face of the u grid intersects the cell center of p but the east face does not. The volume of the u cell and p cell are equal, except shifted. In that case, the distance of the east/west faces from the cell center of u will be different.

Are these 2 discretizations sound? Is there any preferences of one over another?

Thanks
