Practical Grid Generation Tools with Applications to Ship Hydrodynamics

This paper presents 2-D, surface and 3-D grid generation tools for building structured grids. Algebraic, orthogonal and elliptical grid generation techniques are applied to standard test cases of Numerical Ship Hydrodynamics: a surface grid on the P4119 propeller blade for a boundary element method and volume grids for the viscous flow calculation around the KVLCC2 tanker at model and full scale Reynolds numbers. Special emphasis is given to the possibility of blending the different grid generation techniques to optimize the deviations from orthogonality and the grid line spacing.
