Class Objectives
/Class Outline Numerical analysis has been developed as development of computer resources.
Computational fluid mechanics (CFD) has also become useful for not only study but also R&D (Research and Development) in industry in terms of CAE (Computer Aided Engineering).  In this class, you learn mainly the fundamentals of CFD.

(1) To learn fundamentals of numerical schemes of differential equation.
(2) To learn and understand fundamentals of compressible/incompressible flows through numerical solutions.

Class Schedule lesson1 Introduction.
lesson2 Basic of finite difference. Accuracy and error of finite difference, Explicit and implicit schemes
lesson3 Partial Differential Equation (1) : Basic of advection equation
lesson4 Partial Differential Equation (2) : Advection Equation, CFL number. Diffusion equation
lesson5 Partial Differential Equation (3) : Iteration, Poisson equation
lesson6 Incompressible Flow (1) : Numerical method for Navier-Stokes Equation (Review of fluid dynamics, Fundamentals)
lesson7 Incompressible Flow (2) : Numerical method for Navier-Stokes Equation (MAC/SMAC method)
lesson8 Summary of the first half
lesson9 Conservative/Non-conservative forms, Conservation in numerical analysis
lesson10 Compressible Flow (1) : governing equations, characteristic curve, centered expansion wave
lesson11 Compressible Flow (2) : shock wave, analytical solution of shock tube problem
lesson12 Numerical solution of 1D compressible flow 1; LAX scheme
lesson13 Programing practice 1; Lax scheme
lesson14 Numerical solution of 1D compressible flow 2; HLL scheme
lesson15 Programing practice 2; HLL scheme

Learning techniques to be incorporated 　

Suggestions on
Preparation and
Review It is better to review the followings:
(1)-(2) Fluid Dynamics, Taylor expansion
(3)-(5) Ordinary/Partial differential equations
(6)-(7) Incompressible flow
(10)-(14) Compressible flow

It is also important to review the computer language【Fortran90】that has already been studied in the class "Computer Programming". Fortran90 and its compiler are also used for practice in this class. It is also good to read documents given in this class for preparation and review, and to look for references in the library.

Requirements It is recommended to have taken fluid dynamics classes and Computer Programming.
Please Install a fortran compiler and a graphing software such as gnuplot in your own PC in advance.

Grading Method Short practices or homework, and report, term examination, etc are taken into account, then, 60% is required to pass.
