Thorsten Liebig 92d60b3204 fix in cylindrical multigrids: check for valid number of subgrids 2011-03-14 10:37:12 +01:00
Thorsten Liebig 20d6547235 MPI: added cylindrical multigrid support 
The cylindrical multigrid scheme needed a workaround:
An additional barrier is necessary to prevent a simultaneous MPI comm access.

Sebastian Held d31b3ffbb2 updated debug dumps 
The debug dump routines do not work correctly in cylinder coords (--nativeFieldDumps may help)!

Thorsten Liebig bd4794ecc4 NEW: cylindrical multigrid FDTD 
this is a new multi grid approach for the cylindrical FDTD.
The FDTD domain will be split in two regions in radial direction.
The "inner" region will have half as many disc-lines in alpha direction and therefore allow for a much larger timestep which increases the simulation speed.

Todo:
- currently only a homogeneous disc is allowed in alpha direction
- some extensions have to be tested and prepared for this approach (e.g. pml)
- speed enhancement and more efficient memory usage
- lots and lots of testing...
