I want to calculating eigenvalues and eigenvectors by Lnaczos reduction method for using in unsteady aerodynamic field. At first, I simulated cavity flow by using first order implicit method. Incompressible Navier-Stokes and virtual compressibility were used for solving governing equations. Some results of this work were shown.
