Case 02 overview Case_02 series: Central injection of a square plate Case_02a Description Isotropic central injection without vent Case_02b Orthotropic central injection with vent Case_02c Orthotropic central injection with varying vent state Case_02d Case_02e Orthotropic central injection with varying vent state controlled by trigger manager One shot filling simulation objective ? Injection point creation using Remeshing tool ? Permeability directions awareness and definition in RTM ? Vent boundary condition awareness ? Vent role understanding in RTM ? Trigger manager application in RTM ? how to achieve a very quick estimation of the filling time and location of the last points filled Copyright ? ESI Group, 2009.
