Breaking Solitary Waves

Dear Visitors,

Thank you for visiting my personal homepage at my university. My name is Dr. Didit Adytia, I am a Lecturer and Researcher at School of Computing at Telkom University (Tel-U), Bandung, Indonesia.

Since 2007, I have been working on mathematical modelling of water waves, especially in developing a mathematical model so-called Variational Boussinesq Model (VBM) for simulating very long waves such as tsunami up to very short waves such as wind waves or irregular waves in deep water. I have gained most of the knowledge when I did my PhD in the Applied Analysis (AA) Group in Dept. Applied Mathematics of University of Twente, The Netherlands (2008-2012), and was continued by a Post-Doctoral position in the same group (0.5 fte, 2012-2016).

At the same time during my PhD and PostDoc, I was a senior researcher in a private research institute Laboratorium Matematika (LabMath) Indonesia in Bandung. In LabMath-Indonesia, I was the main developer of a water wave software called HAWASSI-VBM (Hamiltonian Wave-Ship-Structure Interaction – Variational Boussinesq Model). The software is designed for simulating water waves in a wave tank, harbour design, as well as simulating waves in deep water. The software is available online since September 2015.

Besides research activities, since December 2012, I started a startup who provides services in coastal engineering area so-called NeXT Ocean Indonesia (NOCI) with LabMath-Indonesia as one of share holders. In NOCI, we were working on modelling of water waves for meteorology and (physical) oceanography (metocean) desktop study. We use phase-averaged wave model as well as phase-resolved wave model as the tools.  Since July 2016, my project works in NOCI has been replaced by a unit called NEXT WAVES – INDONESIA (www.NeXTWaves-ID.com) or NWI. NWI serves as a bridge between my scientific researches and practical (commercial or non-commercial) projects related to the coastal engineering area, meteorology and oceanography.

Starting from the 1st June 2016, I am a lecturer and researcher in School of Computing (SoC) in Telkom University (Tel-U). My research topics are in the area of water wave modelling, Boussinesq-type of equations, Variational Method, Finite Element Method (FEM), Soliton of Boussinesq eq, Tsunami, Hydrodynamics Flow Models, Storm Surge, Non-Hydrostatic Wave Model,  Staggered Finite Volume Method and parallel computing. I am now developing a Boussinesq model for fully nonlinear dispersive with breaking, runup, bottom motion and wind disturbances as well as improving non-hydrostatic wave model for dispersion optimization etc. For High Performance Computing (HPC), I am interested in developing a wave forecasting system.
