Systems, Analysis and Computational Sciences

Ruddy Kurnia is a postdoctoral researcher in the Applied Analysis (AA) group in the Department of Applied Mathematics at the University of Twente.

His main research area is variationally consistent modelling and simulation of water waves. He developed a software that so-called HAWASSI-AB. The software is especially suited for 1HD wave tank simulations (with varying depth, run-up) and probably the best for 1HD irregular (breaking) waves. Now, he concentrates on the extension of the software for simulating coastal waves and for calculating forces on fixed or moving structures.

He also works as a researcher in LabMath-Indonesia (, an independent research institute in Bandung.
