PIAS module: Hulltran

Hulltran is PIAS’ module for global hull form transformation. Given a PIAS-defined hull shape (the “parent hull”), Hulltran will generate a derived shape (the “daughter”) with user-modified parameters, viz. block coefficient, midship coefficient, Longitudinal Center of Buoyance and main dimensions length, breadth and draft. Main dimension scaling is unlimited, while the changes in shape parameters are limited in the sense that daughter should more or less resemble the parent (e.g. a change in block coefficient of, say, 0.05 and in LCB of some 2-4%). Yet, given a applicable parent hull, generating a daughter hull is a matter of seconds.
