after the total success of IH Cantabria's training courses on numerical modelling of wave-structure interaction, we are very proud to announce a new edition of the IH2VOF and IHFOAM courses, this time in New York City.
IHFOAM, what makes it different from the rest of OpenFOAM solvers is a wide collection of boundary conditions which handle wave generation and active absorption at the boundaries, without the use of numerical damping areas. These specific boundary conditions allow generating 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 level or agitation.
Currently the model can be applied to solve any impervious structures, both static and dynamic (floating structures). Some examples that have been simulated include: wave interaction with obstacles as vertical 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 will be provided within a training course, which will cover the usage of IHFOAM with specially designed pre-processing and post-processing tools, guidelines for using the model in coastal and offshore applications and a great number of benchmark cases to solve along the course.
You can find the complete model capabilities, along with the course details and the registration form on the following website:
IH-2VOF is an extensively tested and validated 2DV RANS model which uses the VOF method. It can solve flow within porous media by means of the VARANS (Volume-Averaged RANS) equations. Wave generation including the most used theories is implemented for several procedures: Dirichlet boundary condition, moving boundary method (pyston-type wavemaker replication) or internal wave maker (mass source function). It features active and passive wave absorption. Passive wave absorption is defined by a dissipation zone, and was originally designed to work with the source function. Active wave absorption is a more recent advance, as it absorbs waves on the boundary (moving or not) without adding significant computational cost to the model.
The model can obtain the VOF function, velocity and pressure fields and turbulent magnitudes k and epsilon in any cell. The specific tools designed for post-processing can aid the designer of coastal structures to check the stability and functionality. This includes, but is not restricted to, run-up, overtopping, transmitted energy or evolution of the forces, moments or safety factor coefficient on a structure.
The source code will be provided within a training course, which will cover the usage of IH-2VOF with a specially designed all-in-one GUI, guidelines for testing coastal structures, a great number of bechmark cases and post-processing tools.
You can find more details about IH2VOF and the course on its website:
Both courses will be held at Moffatt & Nichol Engineers office in New York City (NY, USA) between October 14th-15th (IH2VOF) and 15th-18th (IHFOAM).
Please be aware that the places are limited and the deadline for registration is 7th October 2013.
Discount rates are available for academic institutions and when enrolling in both courses.
Participants are requested to bring their own laptops. For the IHFOAM course you must ensure that your PC is able to boot using a Live USB.
We look forward to seeing you in NYC.
