 11 Interface In case of a COINC mesh, switch all interfaces from EQUIV to COINC 11 Interface In case of a COINC mesh, switch all interfaces from EQUIV to COINC (except in case two domains belong to the casting). Create or choose interfaces heat transfer coef. among the interface DB i) standard if you are interested only in filling and ii) die combo if you want to make several cycles)

 16 Boundary Conditions Create new velocity condition by Add Again by Propagate Select surface 16 Boundary Conditions Create new velocity condition by Add Again by Propagate Select surface

 17 Boundary Conditions Fill the velocity BC with the inlet velocity of your process (if 17 Boundary Conditions Fill the velocity BC with the inlet velocity of your process (if you know only time of filling use velocity calculator) Enter time of filling and select all casting volumes. This will calculate the inlet velocity in order to have the right filling time

 18 Boundary Conditions As velocity and temperature conditions have the same surface, you can copy 18 Boundary Conditions As velocity and temperature conditions have the same surface, you can copy the surface selection Select Velocity push Copy, select Temperature push Paste and Store it
