All separate mold components (molds, core, sleeves, pouring cups, chills) are easily assembled in QuikCAST. An automatic volume mesh generator is provided to generate the block-structured mesh used for mold filling and solidification in just a few minutes.

Specific Process

Continuous Casting
ProCAST provides a complete solution for continuous and semi-continuous casting process, including Direct Chill (DC) casting simulation. The software can simulate steady-state conditions as well as the initial and final stages of continuous casting processes. MiLe algorithm is also available to study through the continuous casting process. ProCAST also offers a unique capability: the user functions which allow more advanced end users to program their specific process requirements. For example, user functions allow you to define boundary conditions as time, temperature and space-dependent in order to accurately model any specific casting process.
Centrifugal & Corioli’s force are accounted for in ProCAST to model vertical centrifugal castings, including the effect of these forces on porosity prediction.
Lost foam
ProCAST includes all of the required features to take into account the effects of liquid metal and foam interaction during a lost foam casting process.
Semi-solid modeling
ProCAST is equiped with different models to address the various physics of Semi-solid modeling.
Core blowing
Developed in collaboration with: Ashland, CTI, CTIF, IMFT, Infun, Laempe, Teksid and Weir Foundries The Core Blowing module predicts blowing and gassing defects including incomplete fills, low compaction and poorly hardened areas.

This application will automatically run a set of calculations accounting for this natural variation and provide the user with a process window, showing the maximum and minimum variations allowed in the process while still obtaining the desired results

Physics - Advanced Analysis

Thermodynamic Databases
A ProCAST szoftver teljeskörű megoldás kínál a folyamatos és félfolyamatos öntésvalamint a bugaöntés szimulációjára. Számítható a folyamatos öntés gyártásindítási-, üzem közbeni- és leállási folyamata. A folyamatos öntési tanulmányozásához rendelkezésre áll a MiLE algoritmus is. A ProCAST lehetőséget teremt a felhasználók számára, hogy speciális követelményeik alapján határozzák meg a gyártási paramétereket. Például lehetőség van a peremfeltételek beállításra az idő, a hőmérséklet és a geometriai hely függvényében, melyek segítségével bármely specifikus öntészeti folyamat modellezhető.
Stress Solver
ProCAST allows a unique coupling between thermal, flow and stress calculations. The full analysis is performed simultaneously on the same mesh. With ProCAST you can investigate the thermal shock on the tooling during mold filling as well as the influence of gap formation between the casting and the mold during solidification. Hot tears, plastic deformations, residual stresses and distortions are some of the issues which are being tested by our customers.
Gas & Microporosity
Developed in collaboration with: Assan, Doncasters, Elkem, EPFL, Hydro Aluminium, Pechiney, Rolls-Royce, Sintef, Snecma and VAW. Most simulation solutions restrict porosity predictions to shrinkage porosity. ProCAST is the first commercial software that implements a physics-based approach for the modeling of shrinkage and gas porosity. It includes a gas segregation model along with the proper treatment of solubility limit and pore nucleation.
Microstructure & Heat Treatment

Microstructure formation is an important phenomenon affecting the end properties of an ‘as cast’ component. ProCAST allows for the calculation of the types of phases present - the volume fraction of the phases, the grain size, and grain shape - which all determine the mechanical properties.

The solid state phase transformation and the resulting mechanical properties during heat treatment can also be simulated with ProCAST using models based on Time- Temperature-Transformation (TTT) or Continuous Cooling- Transformation (CCT) diagrams.

The microstructure solver also calculates the macro-segregation based upon the composition of the alloy.

Originally developed by Rio Tinto Alcan, a heat treatment advisor calculates the mechanical properties (YTS, UTS, E% and HB) throughout the entire range - from T4 through T6 and T7 - based on Mg variation and aging parameters for the most commonly poured aluminum A356/357.

Grain Structure
Developed in collaboration with: ABB, AETC, EPFL, Howmet, PCC, Rolls-Royce and Snecma.

Grain structure of ‘as cast’ components are important for controlling casting conditions and optimizing component performance. ProCAST computes grain structure, including columnar to equiaxed transitions, for any dendritic alloy. It allows controlled solidification conditions to generate single crystal or directionally solidified grain structure. ProCAST couples a Cellular Automaton (CA) model with the Finite Element (FE) heat flow computations. For this reason, the grain structure module of ProCAST is often referred to as the CAFE module by industry experts.
