A Prime on Web-Based Simulation

Abstract

A web-based approach gives advantages regarding sharing, compatibility, open source development and interactivity of engineering simulations. This work introduces the approach with a simple damped harmonic oscillator, presenting mathematical formulation, numeric solution method and visualization of the results both in graphical and in 3D. Vessel.js, a more advanced JavaScript library, is used to exemplify web-simulations of complex marine engineering problems, such as vessel motion with six degrees of freedom in calm water and vessel motion with mooring lines. A gallery of open source simulation for conceptual ship design and marine engineering is presented, with detailing of three other examples previously developed: motion response of multiple vessels in regular wave, simulation of pendulum motion of a lifted load and simulation of fuel consumption in transit. A next step of the work intends to focus on further development of time-domain models for maritime and subsea operations in general. The paper closes with a call for future digital twin applications to be developed in open web-based platforms.
