Outputs for Low Lou 1 and 2 are attached below. Outputs for Titov Demoulin 1 and 2 are too large for upload to the twiki, but they can be downloaded here:


  1. Output for case 1 and 3 (LowLou1 and TitovDemoulin 1), both run with relax2 23 then relax2 0, gave "non-zero exit status" error. However, this was found to be a typo on the exit message - a 1 instead of a 0 - and was not indicative of an error. The typo has been fixed and uploaded to CVS.
  2. Cases 1 and 3 (with relax2 23 and then relax2 0) calculate the magnetic field over the photospheric boundary, plus the lateral and top boundaries, i.e. a six-sided problem. Cases 2 and 4 (with relax2 22) calculate the magnetic field over the photospheric boundary only. As expected, tests on the single boundary datasets (cases 2 and 4) were faster than those of the 6-sided problems (cases 1 and 3).
