COURSE TOPICS

DAY 1:  6th September 1999

r    Introductory remarks.  Why  numerical methods?  Classification
of numerical methods.

r    Partial differential equations of fluid mechanics and heat
transfer.  Classification, boundary conditions, and well-posed
problems.

r    Basics of finite difference methods.  Spacial discretization:
Taylor series and point collocation, control volume formulation,
finite volume formulation, and compact differencing.  Temporal
discretization:  CTCS Richardson method. FTCS explicit method, BTCS
implicit method, Crank Nicholson, Runge Kutta methods.  The Thomas
algorithm for tri-diagonal equations.

r    Stability analysis:  discrete perturbation method,
Fourier/Von-Neumann method, matrix stability analysis, and modified
equation.  The Courant Frederich Levy (CFL) and other stability
criteria.

DAY 2:  7th September 1999

r    Analysis of truncation error:  dissipative error, conservative
property, dispersion error, transportive error, aliasing and
anisotropy.  Effects on spatial resolution from differencing
convective and diffusive terms.

r    Methods for transient multidimensional problems:  fractional
steps, ADI, and approximate factorization.

r    Matrix methods for steady state problems.  Norms and
conditioning number.  Direct methods:  Thomas algorithm,
Gauss-elimination, and LU decomposition.  Iterative methods:  Jacobi
iteration, Gauss-Seidel, SOR, method of lines, Multigrid methods and
minimization techniques.

r    Applications to model equations: diffusion equation, Laplace
equation, and Burgers equation.  First, second and higher order
upwinding.  The QUICK scheme and its derivatives.


DAY 3:  8th September 1999

r     Methods for Incompressible fluid flow and heat transfer:
vorticity-stream function derived variable approach, and the SIMPLE
family pressure correction algorithms.

r     Transformation of the governing equations to body-fitted
coordinate system, conservative and non-conservative formulations.
Example of the equivalence of finite volume and finite body-fitted
difference control volume formulations in 2-D heat conduction.

r     Grid generation method.  Algebraic grid generation methods:
some explicit transformation equations for grid control, Lagrange
transfinite interpolations methods, and Hermite transfinite
interpolation methods.  Partial differential equation.
