% to be run before run_test.sli

%  Setup:
%  - 5x5 -> 5x5, extent 1.05 x 1.05 : 
%    Similar to _11, but with minimally enlarged extent, avoiding overlaps
%  - nodes "freely placed" at regular grid locations
%  - rectangular mask ll: [0.,0.] ur: [0.6,0.3]
%  - anchor [0,0]
%  - periodic BC
%  - should give identical results to reg_mask_rect_11.sli
