Development of an Immersive Coastal Hydrodynamic Simulation Environment
Abstract
Boussinesq-type models found in many applications are high-order variations requiring similarly high-order numerical schemes. While" these approaches provide the research-level accuracy needed for certain studies, they do not provide a means for rapid computation;" real-time simulations of a modest coastal region can only currently be acheived with parallel processing on dozens to hundreds of c"ores. Building off a previous ONR project, we propose to utilize a modified form of one of the earlier versions of the Boussinesq-ty""pe model (circa early 1990s), but combined with recent numerical solution and visualization techniques to maximize computational sol""ution speed and user interactivity. In this project, we propose to conti""nue the development of the Celeris model. This development will be two-fold. First, numerous modifications, additions, and enhanceme""nts will be made to the current version of the code. These changes will be directed by the needs of Navy applications, and will gene""rally be in the area of model facilitation, or making the model easier and ""cleaner"" to operate for the end user, who may not necess""arily be a technique expert in coastal hydrodynamics. Secondly, we propose to port the existing Celeris code to a new platform. The" current version of Celeris is restricted to Windows computers and has some restrictions on the tpes of potential interactivity. We" propose to port the code to the Unity plaform, allowing for use on any operating system and development of next-generation visualiz""ation and interactivity, including immersive virtual reality. Specific outcomes of the proposed effor"t include: visualiztion of breaking and wave-induced currents (e.g. 2-min average current field); easy and immediate modification of" the incident wave condition; simplification of the user interface with the non-technical person in mind, including inputs in feet a""nd button to load new bathmetry files; compiling the model for different operating environments, such as iOS or Linux; ability to cl"ick on the wave field and have a subpanel or subplot pop out showing the time series of water surface elevation (or speed) at that p"oint; and development of the ability to use teh model in a Virtual Reality (VR) environment, where the user would be able to fully i"mmersed in the simulated coastal environment.
