Abstract
SHPHUL generates finite element models of a ship hull from body plan coordinates. The model is generated by dividing the hull into a number of sections based on groupings of the body plan contour lines displayed on a terminal screen. Each section is modelled by the use of 4 or 12 noded panels. The 4 noded panels can be skewed or warped between body plan lines. Curvature is represented by the use of the 12 noded panels. The nodes are located with a terminal cursor after body plan contours are selected and displayed on the terminal screen. The panels are then gridded with predefined beams representing frames and longitudinal beams and triangular or rectangular plate elements. Each gridded panel can be made a substructure. Then each hull section is formed as a series of substructures. Transverse and longitudinal bulkheads are formed in a similar manner. Each panel is reduced to master nodes at section boundaries. All the sections are assembled to form the total hull model. An option within the program will generate each section and bulkhead as an individual unsubstructured finite element model which can be assembled later as a single total structural model. The finite element model files created are in the format required by the finite element program VAST thus enabling a structural analysis to be performed as defined by the loading conditions.
