Abstract

A potential-flow solver DIFFRACT written in FORTRAN has been used to analyse the interactions between waves and offshore structures in frequency domain. The program is based on higher-order Boundary Element Method. Meshes generated by some commercial and free pre-processors (e.g. GAMBIT and SALOME) can be imported into the potential-flow solver to carry out hydrodynamic analysis. In this poster, main capabilities of DIFFRACT have been demonstrated in several practical applications.

Following numerical results can be provided by DIFFRACT
• First- and second-order wave forces on structures
• First- and second-order free surface elevations around structures
• First-order motions of single and multiple floating bodies
• Constraint forces between interconnected fixed/floating bodies

Many papers have been published basing on the numerical results from DIFFRACT and a list of publications can be found at http://www.mendeley.com/groups/2020743/4diffract/papers/. More features will be developed in future work.
