Duncan_vdH New Member Duncan Roy van der Heul Join Date: May 2010 Posts: 26 Rep Power: 15	I would like to know if it is possible to use OpenFOAM's overset mesh algorithm to model a piston in a cylinder: a case where the background domain and the foreground domain have boundaries that partially coincide. I understand that the foreground domain may not extend beyond the background domain. Thanks in advance and best, Duncan
