Description
Plot3d mesh (ascii format) converter.
Plot3d mesh (ascii/formatted format) converter.
Work in progress! Handles ascii multiblock (and optionally singleBlock)
format.
By default expects blanking. Use -noBlank if none.
Use -2D <thickness> if 2D.
Niklas Nordin has experienced a problem with lefthandedness of the blocks.
The code should detect this automatically - see hexBlock::readPoints but
if this goes wrong just set the blockHandedness_ variable to 'right'
