HydRA - Hydrodynamic Response Analysis

HydRA, short for 'Hydrodynamic Response Analysis' is a code that is being developed within my research group at IIT Madras to simulate linear and nonlinear dynamics of marine and offshore structures in the ocean. The idea behind the development of this code is twofold. On one hand, the code will be used extensively for research purposes and will be constantly updated based on the latest research being performed at our group. At the same time, the web application is being provided for free to allow students or professionals in the industry to simulate fluid structure interactions and visualize the results without the need to depend on a commercial software that involves a steep learning curve. Futhermore, the user need not have a high end computer to run simulations as the computations are performed on our servers. As the software is being primarily developed by undergraduate students and with an intent to make it easy for other undergraduate students to use it, the web application is structured in such a way that minimal effort is needed to start using this tool. 

HydRA also includes a frequency domain panel method code so that time and frequency domain simulations can be performed and visualized using a single code.

The video below is an interaction with students that discusses about the current features of HydRA and the planned developments in the future. If you are interested in contributing to this project, contact me by email. Some of the code developments planned currently include:

HydRA Validation

The simulation software HydRA has been validated against WAMIT. The following presentation shows the comparisons between HydRA and WAMIT for the following quantities in both single body and multi-body scenarios:
