Workshop 4.2Tetra Meshing - Valve;Set Working Directory;Build Topology;Create Parts;Continue breaking the geometry into Parts Turn off the VALVESPHERE part in the Model tree. This will expose the Valve Inside Create a new Part, VALVE and add the 6 surfaces of the valve head to this Part Separate parts makes it easier to visualize segments of the model by turning parts on and off Separate INLET and OUTLET Parts are essential to apply individual boundary conditions. The BC’s are applied to the part names. Note: the Parts are color matched with their names in the model tree;Create Material Point;Build Topology;Global Mesh Size;Set Surface Mesh Size Mesh - Surface Mesh Setup Click the Select surface(s) picker The Select geometry popup tool bar appears, use the Select All icon to select all the surfaces Set the Maximum size to 4 Click Apply Right mouse click on Surfaces Tetra Sizes in Model tree to see a visual display of the sizes;Curve Mesh Size;Create Density Box to locally control volume mesh size Surface and curve sizes only control mesh sizes on those entities. Densities control mesh sizes within a volume. Mesh - Create Mesh Density Set the Size to 2 Set the Type to Entity bounds Use the Select geometry picker The Select geometry popup tool bar appears, use the Select Items in a Part Icon to select the ValveSphere Part Accept, then Apply;Compute Mesh;Cutplane View;Check Mesh Quality
