Default distance between adjacent nodes
Posts: n/a
Hi guys! I'm trying to simulate a flapping and deforming fin with fluent (dynamic mesh, unsteady). Since the length of the fin is fixed even if it's moving, how can I tell fluent (in my DEFINE_GRID_MOTION UDF) that the distance between adjacent nodes is constant? Any suggestion will be very appreciated!!!!!!! thank you! elisa
