Celeris is the first interactive coastal wave simulation and visualization software. It is an open source software which needs minimum preparation to run on a Windows machine. The software solves the extended Boussinesq equations using a hybrid finite volume - finite difference method and supports moving shoreline boundaries. The simulation and visualization are performed on the GPU using Direct3D libraries, which enables the software to run faster than real-time. Celeris provides a first-of-its-kind interactive modeling platform for coastal wave applications such as nearshore tsunami evolution/inundation, and nearshore wind wave modeling. It supports simultaneous visualization with both photorealistic and colormapped rendering capabilities. Celeris is validated through comparison of its results with several standard benchmarks for non-breaking and breaking waves.

Development of Celeris was partially supported by research grants from the Office of Naval Research and the National Science Foundation. The software was created and is being maintained by PhD Candidate, Sasan Tavakkol, working with Prof. Patrick Lynett at the University of Southern California.
