AMR and conductivity tensor does not work with poisson solver

[jacksonross1024]

Any AMR value not 0.0 will cause invalid values to the conductivity, resulting in grey values for plots. ConjugateGradient solver goes grey the entire region, but jacobi (with a single step) shows grey lines propagating out of cells with magnetic vector along cartesian axis (e.g., the diagonal parts of the tensor)

Hello, this is unfortunate. Could you please upload an example script which reproduces the problem? It can also be informative to share the specs of your setup (i.e. Windows of Linux? Python and CUDA version..). This will help diagnose this problem. Thanks!
