SCHEME
- implement Flux-CT scheme for the staggered magnetic field
integration;
BLOCK STRUCTURE
- use more space efficient storage of the variables, which means
storing only staggered components of magnetic field; cell-centered
components are calculated only when necessary;
EVOLUTION
- remove loops in the field updates; operations are performed on the
arrays;
BOUNDARY CONDITIONS
- remove loops in the bnd_copy; operations are calculated on the whole
array now;
INTERPOLATION
- subroutine magtocen() has been rewritten to avoid problems with the
array allocation; now as an argument we enter the array of all
variables; subroutine uses indices for the face-centered and
cell-centered magnetic field components internally;
MAKE
- add flag defining Flux-CT scheme;
PROBLEM
- use predefined array variables instead of allocated;
