%RUNME - test deck for ISSM nightly runs
%
%   Usage:
%      varargout=runme(varargin);
%
%   Examples:
%      runme;
%      runme({'ice'});
%      runme({'ice','cielo_serial'},{'diagnostic'});
%      md=runme({'cielo_parallel'});

% 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.
