This folder contains two .m files. 

BuildSimulation.m is used to generate Geometry.map2D and Signal.slg.  

WriteCircularReceivers.m is a small script that writes 128 receivers one by one following a circular pattern, which would otherwise be rather cumbersome to enter manually in Parameters.ini2D.  WARNING: this file adds receivers to a Parameters.ini2D file which is supposed to have NONE. Therefore, this script should not be launched twice, or launched on a Parameters.ini2D file that already contains receivers. In case of multiple lists of receivers, only the first list will be taken into account by SimSonic2D.
