ESI PROCAST V2008
ProCAST is a complete modular software system that can be included to expand the application modules and engineering tools to meet the challenging foundry business needs. Various modules are highly specific, targeted at a specific process steps:
· Flow solver - filling process simulation, including the semi-solid materials, EPC and the centrifugal casting process;
· Heat transfer solver - and the solidification contraction forecast trends, including the option of radiation;
· Solver stress - heat stress and deformation.
· In addition, the senior Kim Sang-exclusive option to be able to predict:
· Pores and micro-cavity;
· Carbon iron alloy microstructure grain structure.
ProCAST a total of nine modules, the following were set accordingly.
Pre-processor PreCAST
ProCAST through the graphical user interface can define a variety of boundary conditions. These feature-rich can accurately simulate all the casting situation. Selected need impose conditions for the geometry of the border region can click and choose automatic extension of the implementation. User-defined data can not change, or at any time or temperature changes.
Simple and direct definition of boundary conditions ProCAST materials database provides a scalable database material can be used to simulate most of the alloy, from steel to aluminum and iron, cobalt-based, copper, magnesium-based, nickel-titanium and zinc-based alloys . At present, the materials database is also still continuing to expand through industry-proven sound parameters will be added in a timely manner.
In addition, ProCAST also has a unique database of thermodynamics. The database allows users to directly import the chemical composition of alloys, auto-generated simulation of the necessary data.
