砂模鑄件模擬時注意事項

Turn off Internal Heat Transfer Coefficients
關閉材料表中的內部熱傳係數計算
Use a low External Heat Transfer Coefficient: Around 1.5 BTU/Hr-sqft-F
設定較低的外部熱傳係數--建議值為9~12
Only use as much sand as is necessary to absorb the heat (1” for small castings, 4-5” for large castings)
小型砂模鑄件在模擬時,建議設定的砂模的厚度為30-50mm; 大型鑄件砂模則設定在100-150mm之間
Generally make a rectangular mold when meshing
在網格時,設定模子種類為"矩型"
