Demonstrate jacobbi, gauss-seidel and SOR methods to solve a sample problem of a diffusion discretised by finite volume method (central differencing).
Also included, the determination of optimum omega value for minimum iteration in SOR method by comparing it with the gauss-seidel method.
cfd1.m-initialise the mesh number and the boundary conditions.
abc.m-calculate the coefficients
jacobbi.m, gs.m, sor.m
-solve the distribution by the respective method.
mesh.m-match the mode position with its respective assigned value.
optimum.m- a function to determine the 'best' optimum omega value for use in the SOR method. |
