Ship Wave
Interaction
My PhD researches started
with the in-house CFD code RIAM-CMEN. My contribution is in two aspects. First, the serial RIAM-CMEN code was successfully parallelized using the domain decomposition
method with non-blocking MPI communication. Second, to treat
slender bodies in Cartesian grid efficiently, a panel approach based on the
marching cubes method was proposed.
The improved CFD method has been applied for prediction of the hydrodynamics of
ship wave interaction and floating offshore wind turbine platform.
