% This file can be run to check that the current version of issm is giving 
% coherent results. This test deals with an icesheet with icefront for a 3d model. The geometry 
% is square. Just run this file in Matlab, with a properly setup ISSM code. 
% The results of this test will indicate if there is a difference between current computations 
% and archived results.

% Errors  between archived results and the current version will get flagged if they are not within 
% a certain tolerance. The current tolerance is 10^-12. If you have good reasons to believe this 
% tolerance should be lowered (for example, if you are running single precision compilers?), feel 
% free to tweak the tolerance variable.
