- the PDRsetFields utility processes a set of geometrical obstructions
to determine the equivalent blockage effects.
These fields are necessary inputs for PDRFoam calculations.
After setting up the geometries, the -dry-run option can be used to
generate a VTK file for diagnosis and post-processing purposes.
- this is an initial release, with improvements slated for the future.
NOTE
- the field results may be less than fully reliable when run in
single-precision. This howver does not represent a realistic
restriction since the prepared fields target a combustion
application which will invariably be double-precision.
