program testAAH

PURPOSE

Checking: cgca_sld, cgca_nr

DESCRIPTION

Checking solidification with 640 nuclei, coarray (100,100,100)[4,4,4]. This gives the desired resolution of 1e-5. Therefore run with 64 images... or try other values...

NOTES

The program must be called with 2 command line arguments, both positive integers. These are codimensions along 1 and 2. The number of images must be such that codimension3 = num_images()/( codimension1 * codimension3 ) is a positive integer. Example: 

      cafrun -np 16 ./testAAH.x 2 2      ! OpenCoarrays

or 

      ./testAAH.x 2 2                    ! Intel, Cray

which will make the third codimension equal to 16/(2*2)=4.
