Entry Price Point: $18,000 for an annual lease or $45,000 to pur- chase the basic CAP sand package for meshing, fluid flow and solidification modeling of sand cast processes. Overview: CAP is based on the 3-D finite element method. Its auto- matic CAP Smart Mesh Generator creates casting geometry with fine ele- ments and modeled mold components with coarse elements. Smart Mesh technology minimizes the computer resources necessary to simulate real world processes. Te same mesh can be used with all CAP components. Set up, execution and review of all CAP simulations are graphical user interface-driven. Newest Features: A significant
portion of improvements center around automating or semi-automating tasks commonly performed, such as mesh generation, simulation parameter setup, and macros for post-processing. Te most recent improvement is automati- cally running sequential analysis with CAP Commander, a tool ideal for simulation design of experiment. It can execute a set of simulations sequen- tially with minimal user interventions. In the analysis software, EKK has added the ability to evalu- ate the effects of porosity of hydrogen gas concentration in the melt, as well as trapped air distributions from the flow analysis. Software’s Strengths: CAP
originally was developed for high pressure diecasting, but it can model any mold material and casting process, including sand, semi- and low pressure permanent mold, squeeze and
investment casting. Aluminum, iron, magnesium and zinc are the most common alloys. What’s Unique: CAP generates full
multi-component finite element meshes of the complete casting process in minutes, if not seconds. For high pressure diecasting, CAP models the liquid move- ment in the shot sleeve and the effects of intensification pressure on microporosity. Recently, the software has successfully predicted thermal cracks in castings.
