Kursplan för studenter höst 2022

After a successful course, the student shall:

• show familiarity with use of casting simulation in the development of new casting processes
• display knowledge of analytical and numerical methods used to calculate phenomena associated with casting.
• demonstrate comprehension of how material properties and boundary conditions affect the calculation results.

• demonstrate skills of using analytical formulas and numerical programing of heat transport and solidification phenomena in relation to casting of metallic materials.
• demonstrate the ability to use professional software to optimize mold filling and resulting cast material properties.

• demonstrate the ability to chose adequate calculation methods and models for various kinds of cast materials.
• demonstrate an understanding of validation methods to determine if calculation results reflect real phenomena associated with casting.

The course covers trends in programing and simulation of solidification phenomena of cast metals. Examples from applications for process and materials development, solutions of technological problems using casting simulation. An analytical part treats the basic heat transport and solidification. A numerical part treats the heat equation by conduction using the Finite Different Method (FDM). Numerical solution of solidification via the Enthalpy method and associated heat transport is solved with the control volume based finite difference method FDM-CV. Numerical solutions based on 1D formulation are solved in MATLAB and compared with simulation in a commercial 3D simulation software.

The course includes:
• Fundamentals of heat flow and solidification
• Programming the heat flow and solidification
• Use of professional casting simulation software
• Validation of the casting simulation

Teaching consists of lectures mixed with calculation exercises, laboratory work with programming 1D program codes to calculate heat conduction and solidification, laboratory work with commercial 3D program to test optimization of casting and solidification of cast components.
