1、Gravity-SandThis tutorial will guide you step by stn the ProCAST set-up of a sand casting simulation.The geometry used for this tutorial is comcastingsand boxcoresed of a:本指南将指导你在 ProCAST 中一步一步地建立一个砂型铸件模拟。本指南中需要的几何模型包括:铸件砂型砂芯1 Load the sand.mesh min PreCAST1、在 PreCAST 中加载 sand.mesh模型Please enterthe

2、case name under the Case field of the file manager and press the PreCASTPreCAST will loada ProCAST file (d.dat) if it is presenthe current directory. If PreCAST does not findany ProCAST file, it will look for a MeshCAST file (.mesh) with the corresponding prefix. And if there is noMeshCAST file, you

3、 will have to use the Open fileof PreCAST in order to look for the right file.首先在 file manager 中的 Case 区域添入工程名称，点击 PreCAST 菜单。PreCAST 将首先加载一个 PreCAST 文件(d.dat)，如果这个文件在当前目录中。如果 PreCAST 没能找到一个 PreCAST 文件，它将搜索一个带有相应前缀的 MeshCAST 文件 (.mesh)。如果没有 MeshCAST 文件，你将不得不用 PreCAST 菜单中的 Open 文件菜单来搜索正确的文件。2 Check t

4、he geometryPreCAST indicates automatically the number of materials, the total number of nodes and of elements. The unitsand the global size of the mare shownThese information and the volume of the different components are availablehe File- Check geometryoptions.2、检查几何模型PreCAST 自动显示材料的数量，节点和零件的总数。模型的

5、也将显示。和轮廓尺寸这些信息和不同零件的体积在菜单 File- Check geometry选项中。3 Assign material properties to the casting, mold and cores. material, Sand silica to the mold and Steel_H13 to the corehis case, Ductile Iron is assigned to the castings.3、对铸件、砂型、砂芯设置材料参数。在本例中，铸件材料为球铁，砂型材料为硅砂，砂新材料为 Steel_H13 。4 Create and Assign the

6、erfabetn the componentshis case all Apply button.erfahave to be converted from EQUIV to COINC. In order to validate this choice, press the4、创建和设置不同零件的界面在本例中，所有的界面将 EQUIV 转化成 COINC。为了使该项选择有效，点击 Apply 按钮。Once theerfaare created, assign a heat transfer value to eacherface. Typical values are 500 W/m2Kb

7、etn casting and sand and 1000 W/m2K betn casting and steel cores.一旦界面被创建，对每个界面设置一个热传导数值。典型值铸件与砂型界面为500 W/m2K，铸件与钢制砂芯之间为1000 W/m2K。5 Assign the Boundary conditions5、设置边界条件A natural air cooling heat Boundary condition will be appd all around the sand box, a velocity Boundarycondition will be appd and
