* predict the influence of the gating/methoding/casting design on turbulence The aim of modeling the filling and solidification of a casting is to: This allows for calculations profile process changes as a function of time. The problem must be broken into small calculations via either a finite differencing method or a finite element method.
In first principles programs, complex physical relationships and equations are used along with detailed material physical data. Typically, the problem is broken down into many small calculations via a finite differencing method. There are three basic types of computer simulation tools: empirical programs based on experimental results and experience semi-empirical programs based on experimental results in addition to basic physics and physics-based first principles programs that require complex mathematics and accurate material thermophysical data.Įmpirical and semi-empirical programs use tables of experimental results, rules and guidelines and physical and algebraic equations to model a physical process.
If the process of filling and solidifying a mold cavity is accurately modeled, shrinkage cavities and other casting defects can be predicted the effects on metal fluid flow and solidification of changing the gating/risering method or many other process variable can be simulated and molten metal trial iterations can be significantly reduced and used primarily for concept validation. The purpose of simulating any industrial process is to model the underlying physics so that important process variables can be identified and controlled, resulting in significant benefits.
