SYNOPSIS

!$Id: testAAW.f90 380 2017-03-22 11:03:09Z mexas $

program testAAW

PURPOSE

Checking: cgca_clvgp (no CO_SUM version), cgca_clvgsp

DESCRIPTION

Checking probabilistic cleavage propagation with 1 cleavage nucleus in the middle of image 1. Single grain with random rotation tensor. 1-2 cleavage increments. Halo exchange, so cleavage propagation across image boundary. Check crack flank deactivation.

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 ./testAAW.x 2 2      ! OpenCoarrays

      ./testAAW.x 2 2                    ! Intel, Cray

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