Interpolation is the process of estimating the values of a function, when the function's values are known only at a particular set of points. Questions on interpolation in one or more dimensions, as well as algorithms for doing so, should have this tag.

WENO5 scheme in a staggered grid
partial t} = -\frac{1}{r}\frac{1}{dr} \left[f_r^{i+1/2,j}-f_r^{i-1/2,j} \right]-\frac{1}{dz} \left[f_z^{i,j+1/2}-f_z^{i,j-1/2} \right]$
Now, since the velocities aren't defined at $i,j$, I use a simple interpolation … I've tried to do a WENO interpolation of the densities, but that also isn't working as well as I need it to.
Any suggestions on how to handle this issue? …
