Abstract
The report describes the modifications made to improve the efficiency and accuracy of PVAST, a pre- and post-processing programs suite developed for the strength and vibration analysis of marine propellers by the finite element m;ethod. The PVAST blade meshing routines have been modified to produce well proportioned elements. The user has more control over the proportioning of the blade finite elements, in particular with respect to element distortions and aspect ratios. Also, the PVAST module which generates three-dimensional fluid finite element meshes has been enhanced to avoid element fold-over and gross element distortions at the trailing edges for highly skewed propeller blades. The surface panel method has been implemented in PVAST as an option for modelling the fluid surrounding the blade.
