Dear colleagues,

We are very proud to announce the release of the IHFOAM bundle.

What makes IHFOAM different from the rest of OpenFOAM solvers is the Volume-Averaged Reynolds-Averaged Navier-Stokes (VARANS) equations along with the corrected advection of the phases, accounting for the porosity of the cells, that allow the simulation of two-phase flows through porous media. On top of that, a collection of boundary conditions handle wave generation and active absorption at the boundaries, without the use of numerical damping areas. These specific boundary conditions allows the generation of any type of wave in a 3D domain, from the most simple regular waves (Stokes I, II and V, cnoidal, streamfunction...) to complex, real and fully 3D irregular (random) directional sea states.

Active wave absorption has been programmed to work simultaneously with the wave generation to absorb any incident waves on the boundaries. These features do not increase the computational cost noticeably, and there is no need to extend the numerical domain, as it occurs with relaxation zones. Moreover, they allow for longer and more stable simulations without increasing water or agitation levels.

Currently the model can be applied to solve any kind of coastal/offshore/hydraulic structures, both static and dynamic (floating structures). Some examples that have been simulated include: wave interaction with vertical and rubble mound breakwaters, ships, offshore foundations, dam and spillway simulations, open channel flow, etc... Needless to say, a thorough validation with well-known laboratory tests has been carried out and is published in Coastal Engineering.

The source code is provided free of charge, along with a reference manual and tutorial cases. You can find the complete model capabilities, additional materials and detailed instructions on how to download, compile and run the code at IHFOAM web site:

We look forward to having feedback from you.

Best regards,

Pablo Higuera, Javier L. Lara and Iñigo J. Losada
