Post doc Renato Skejic is working with development of medium-fidelity computational methods for added resistance due to waves. This means potential flow methods that are less complicated, faster and more robust than full 3-D non-linear panel methods while still being more accurate than the current linear potential flow methods implemented in ShipX and applied in Gymir. The methods he is aiming at will be computationally fast, but will require input of 3-D hull geometry. The deliverables are expected to be in terms of scientific paper(s) and computer implementation(s) of the method(s). However, final implementation and integration with (for instance) ShipX and Gymir will be outside the scope of the post doc project.
