Release of a new open-source BEM code HAMS as a substitution of WAMIT, AQWA, WADAM, Hydrostar, etc

Dear colleagues and friends,

I am happy to let you know that a new open-source BEM code for wave analysis of offshore structures has been released on GitHub for months. The code is named HAMS (Hydrodynamic Analysis of Marine Structures) and has been developed by me for almost a decade. Last year I decided to release it as an open-source code so as to eliminate the inequality (for those who cannot afford to purchase a costly commercial BEM software) in the continuous research developments related to offshore engineering and the ocean renewable energies, such as offshore wind, wave energy converters, etc.

There are several important features that may attract you to use HAMS:

1. HAMS can read WAMIT *.gdf mesh file and can export the computation results to WAMIT or Hydrostar format.

2. HAMS is written in the OpenMP parallel mode so you can specify how many cores/threads to use before running it. Running a typical case with e.g. 3000 panels may cost several seconds on a laptop for each wave period.

3. HAMS can (at the user's choice) remove the irregular frequencies that Nemoh might not be able to.

4. HAMS is written in a clear code structure using Fortran 90, which will be much easier for further continuous developments by the users.

You can find and download the HAMS code here:

I suggest you fork the entire project so that you will be able to receive the latest updates from time to time.

I wish all of you enjoy using HAMS in your research and daily works.

Best regards,
