In the case of low pressure die casting (lpdc), it is possible to model the liquid bath of metal and to apply a pressure on it (in order to drive the metal in the mold) via injected air. The inject BC allows to specify the amount of injected air。 7 n: U3 s J0 _6 R低压铸造过程:用于模拟空气注入坩埚(liquid bath 液池)进行压力充型。 " A1 | s( B3 s" |% S边界条件设置:inject中设置空气流量
