RegriddingInterpolationLevel

Section Mesh
Type integer
Default regridding_linear

Choose the interpolation order for the regridding. 0 is equivalent to nearest neighbor interpolation. The default is linear interpolation.

Options:

regridding_nearest_neighbor:
Use the nearest neighbor for the regridding. This is faster than the linear interpolation.
regridding_linear:
Use a trilinear interpolation. This is implemented similar to restriction and prolongation operations in multigrid methods. This ensures that both directions are adjoint to each other.
