Learn the Benefits and Limitations of Die Casting Process Modeling and Simulation, including die casting lubricant spray patterns
This series of three NADCA webinars is a brief overview of issues related to modeling and simulation of the die casting process. Emphasis is placed on making a distinction between modeling and simulation and understanding where simplifications necessary to successfully implement simulation software require special attention by the end user.
Part 1 - Background -
The first of three sessions addressing die casting modeling and simulation issues covers basic background material. The relationships between simulation and modeling is introduced with emphasis on the fact that simulation always requires modeling, but modeling does not necessarily require simulation. The concept of simulation is introduced as the numerical solution of models developed from basic models developed primarily from fundamental conservation laws. Modeling issues discussed include definition of problem boundaries, approximation of geometry, restriction of the phenomena (e.g. thermal, flow, stress, etc.) of interest, and the importance of boundary conditions. The special problems presented by widely varying spatial and temporal analysis scales are also introduced.

Part 2 - Selected Technical Details -
The basic equations of physics do not change from one simulation package to another, but the solution procedures may vary. Some of the key differences of finite element, finite volume, and finite difference are briefly illustrated and the pros and cons of each are reviewed. Specialized elements available in many general-purpose CAE packages, but generally not available in casting packages, are also illustrated to help understand why questions need to be asked to fully understand how a casting simulation package is generating certain types of results. Geometry and meshing issues and the impact on the solution are considered. Some of the problems inherent in comparing simulation results with casting results are illustrated including the fact that nearly all such comparisons are qualitative. The session concludes with an overview of typical solution rendering techniques and their pros and cons.

Part 3 - Limitations -
This session is a review of the range of modeling simplifications that are used to make simulation tractable, but then require careful interpretation of the results. Included are time-scale issues and transient versus steady state results including temperature creep; modeling of spray; selection of heat transfer coefficients; technical issues modeling heat loss during fill; cooling line performance, and venting performance. The benefits of special purpose models to provide engineering insight to supplement simulation results in select cases is also illustrated.
