 This quadrangular mesher is based on [[http://www-lacan.upc.es/sarrate/|Sarrate]] algorithm. This method consists in diving the domain in a recursive way until only one quadrangle remains. It is very robust, and enables efficient meshing of complex domains.
+<note important> By design, running twice Gen4 with the exact same parameters does not necessary lead to the same mesh. This can lead to some issues when running a simulation on a computer and trying to load results on another. To avoid this, the mesh generated is saved in a ".gen4" file, which will be read when loading a fac instead of creating the mesh anew. This ".gen4" file is not automatically deleted when cleaning the worskpace, so if you modify your mesh parameters, you must manually delete this file. </note>
