Finite Solutions. Inc.
Finite Solutions, Inc. is the developer of the SOLIDCast[TM], FLOWCast[TM] and OPTICast[TM] suite of casting simulation software Simulation software is based on the process of imitating a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually running the program. .
SOLIDCast[TM] is the world's best-selling solidification modeling software package, with over 585 companies and schools in over 45 countries around the world having purchased the package. The first version, called AFSolid, was released in 1985 and has been updated and expanded on a continuous basis.
SOLIDCast[TM] is a PC-based solidification modeling system that uses the Finite Difference Method In mathematics, more precisely in numerical analysis, finite differences play an important role, they are one of the simplest ways of approximating a differential operator, and are extensively used in solving differential equations.

SOLIDCast[TM] intended for use by the foundry engineer as an everyday tool, which means that we have focused on three specific areas of development: ease of use, speed of operation and accuracy of result.
Using a variety of techniques, we have been able to produce simulations of casting processes which used multi-million element meshes (thus representing the casting geometry quite accurately) and which run in less than 30 minutes on up-to-date personal computers.
The focus of SOLIDCast[TM] is prediction of shrinkage and porosity defects during solidification. For prediction of misruns, cold shuts and other filling-related defects we have an optional fast CFD CFD - Computational Fluid Dynamics solution module called FLOWCast[TM]. This module solves the Navier-Stokes equations The Navier-Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of fluid substances such as liquids and gases. These equations establish that changes in momentum in infinitesimal volumes of fluid are simply the sum of dissipative viscous , and can produce temperature, velocity and pressure information for a mold filling sequence.
SOLIDCast[TM] tracks volume changes which occur (contraction of liquid metal and solidifying metal and, in the case of graphitic irons, expansion associated with graphite precipitation) and simulates movement of liquid feed metal in response to those volume changes. This allows the system to predict the action of risers and the formation of primary shrinkage. Other predictors are used to indicate secondary shrinkage or structural microporosity in the casting.
A special feature of SOLIDCast[TM] is the Riser Design Wizard[TM], which uses simulation results from an unrigged un·rig

Feeding paths are determined by the software, based on simulation results of the casting alloy and mold material in use. Filling and chilling can also be applied. The wizard works with conventional risering, as well as insulating or exothermic exothermic /exo·ther·mic/ (-ther´mik) marked or accompanied by evolution of heat; liberating heat or energy.

Two forms of the disease exist. Tropical sprue occurs in central and northern South America, Asia, Africa, and other specific locations. , runner(s) and gate(s).
OPTICast[TM] is a tool used to automatically guide the simulation process to an optimal result, based on user-defined constraints. You may want to find the highest yield for a part, while maintaining good casting quality. OPTICast[TM] will automatically mesh a model, run a simulation, evaluate results, adjust the model and re-simulate until the optimum condition is found. Optimization results are provided in both spreadsheet and graphical forms, in addition to the optimized model, mesh and simulation.
Using OPTICast[TM], the foundry engineer can start with an initial design and allow the computer to do the work of modifying the design and running simulations to achieve an optimum result.
