In the meantime, the company also focused on building its own internal capability to melt alloys and to create ingot, the input stock for investment castings. This endeavor eventually resulted in the addition of a new titanium production facility, and Precision Castparts soon became the world’s leading manufacturer of large titanium castings as well. At the same time, the company was hard at work developing a process to manufacture titanium castings, adding to its already proven capabilities with nickel and stainless steel alloys. In 1968, Precision Castparts became a public company with the offering of 120,000 shares of common stock to 1,100 new shareholders. It wasn’t long before Pratt & Whitney signed up to incorporate large structural castings into their JT9D commercial engine, and Precision Castparts became a significant participant in the aerospace industry. Air Force C-5 Galaxy heavy military transport, was the first high-bypass turbofan engine and the forerunner of GE’s commercial CF6 family of jet engines, installed on Airbus and Boeing wide-body aircraft around the world. The TF39 engine, designed to power the U.S. Then, in 1967, Precision Castparts was awarded a contract with General Electric for TF39 engine components. That moved the business far ahead of its competition and resulted in several contracts for large aircraft engine castings. The company pushed aggressively to make ever larger structural castings and, in 1962, purchased a vacuum furnace with the capability of pouring a part weighing up to 1,000 pounds. Three years later, the company, owned by Cooley and two other individuals, was incorporated under the laws of the State of Oregon. This venture proved so successful that, by the spring of 1953, the casting division was made into a separate business and named Precision Castparts Corp. The 2D mesh is generated only on the Z=0 surfaces that you identify using the Badge For 2D Meshing operation.In 1949, Joseph Cox, president and owner of Oregon Saw Chain in Portland, Oregon, started a small investment casting business with the intention of making a special cutter for his chain saw products.Įd Cooley, assistant general manager for the company, began to spend more and more time with the casting operation and solicited outside work primarily from local businesses. These surfaces must be part of the source surfaces.ī.Expand the Custom Controls > Surface Control > Controls node.Ĭ.Select the Dominant Element Type node and choose the desired element type. Using a custom surface control, you can generate a mixed mesh (that is, a mesh that has surfaces with different elements).Ī.Create a custom surface control and add to it the surfaces on which you want to have different element types. See Creating the Two-Dimensional Automated Mesh Operation. Parts that are badged as 2D cannot belong to the same region as parts that are not badged.Ĥ.Create an Automated Mesh (2D) operation. Separate regions are created for 2D and 3D parts. See Assigning Parts to Two-Dimensional Regions. See Identifying the Target Part Surfaces for 2D Meshing.ģ.Assign parts to 2D regions. See Transforming Parts to a Coordinate System.Ģ.Badge the 2D parts that contain the Z=0 surfaces. See Manipulating Part Surfaces.įor 2D axisymmetric analyses, the axis must lie on the X-axis and the mesh must also be above the local Y=0 plane. You can also use splitting tools to break out the target surface into its own part surface. If necessary, transform the parent part so that the target part surface lies on the Z=0 plane. 2D meshes are useful for some electric machine and aerospace industry analyses.ġ.The whole part surface on which a 2D mesh is required must be coincident with the Z=0 plane, within a tolerance of 1.0e-6. It is easiest if you go to steve and find an article on how to do 2D or even better the sim file to see.Īlso: Make sure one of the planes is parallel to Z=0!!!įollow these instructions to produce a real two-dimensional mesh in Simcenter STAR-CCM+ from selected two-dimensional part surfaces.Ĭreating a 2D mesh is more efficient and less computationally expensive than extracting a 2D mesh from a 3D mesh. Then go name the inlet, outlet, free stream etc and the airfoil walls. It should put an asterisk on those surfaces once it realizes the planes. make sure to create a separate patch for the top/bottom surface separately and then do detect 2d body. Just extrude the geometry around the airfoil 1cm (length doesnt matter as long as parallel), you dont need the solid airfoil part.
