Tightly Coupled, Unstructured Mesh, Wave and Circulation Models

In between presenting and writing up our work to couple tightly the SWAN and ADCIRC models, I also designed a poster for the hallway outside our lab.

It emphasizes our transition from the loose coupling with structured-mesh wave models to the tight coupling with the unstructured-mesh version of SWAN. The rectangle in the upper right and the triangle in the lower left are meant to “pop” from the sides of the poster, as shown in the picture to the right. By running on the same unstructured mesh, SWAN and ADCIRC can pass information locally, on the same core or across inter-core boundaries, without the need for global communication.

The poster itself is linked below. For more information about the SWAN+ADCIRC model, please visit my Web pages about the coupling. For a copy of our paper describing the coupled model, please contact me, and I would be happy to send it to you.
