We are very proud to announce a new edition of the IH2VOF and IHFOAM courses.

 

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.

 

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.

 

IHFOAM is a state-of-the-art 3D Navier Stokes solver for water waves. The training course covers from all the basics needed to learn to use OpenFOAM, to all sorts of advanced techniques, and tutorial cases not included in the materials released, namely:

 

- Residual monitoring
- Video rendering
- Runtime sampling
- Sampling with Paraview
- Dynamic mesh refinement
- Moving and deforming meshes
- Creating and compiling solvers/libraries/utilities

 

The combined use of IH2VOF and IHFOAM models has proven very convenient in order to save computational cost in 3D simulations. This methodology has been successfully applied in the following paper:

Published in News
Over the last 10 years, IH Cantabria has been carrying out work related to the assessment of environmental impacts generated by anthropogenic activities, using a multidisciplinary approach. Much of this work has focused on the evaluation of the impact generated by urban and industrial discharges, with a special emphasis on outfalls. In this field, IH Cantabria has experts specializing in the management and development of hydrodynamic models, with extensive knowledge of the structure and functioning of aquatic ecosystems and their response to such changes.

Furthermore, IH Cantabria  has participated in the evaluation of impacts of various activities related to water, such as port facilities, offshore facilities, dredgings, etc.

In the last decades IH Cantabria has dedicated an important amount of resources to developing its own next-generation numerical tools to study offshore wave transformation processes  and their effect on port infrastructures. By using these models developed internally , was added to a specific methodology for the analysis and design of coastal infrastructure based on the integration of the different tools and techniques existing study , to get maximum benefit in the identification of variables associated with the functionality and stability of infrastructure design, culminating in an optimal design and quality.

Amongst the numerical models developed by IH Cantabria we can find deep sea to shorelines wave propagation models such as MOPLA or IH-BOUSS. The latter is a nonlinear wave propagation model which uses Boussinesq equations and allows the study of the nonlinear transformation of waves off the coast for entire sea states. MSP and MANOLO models allow studying port resonance phenomena, both in its phase  integrated version (MSP) as well as in transitional phases (MANOLO) IH Cantabria  offers an extense range of Computational Fluid Dynamics models based on RANS equations both in two-dimensional  (IH-2VOF) and three dimensional versions (IH-3VOF e IH-FOAM), which allow the determination of the fotces that the wave exert on conventional and non-conventional structures, and the study of the variables related with the functionality of these structures, such as overtopping.

In the last decade, IH Cantabria has been actively involved in the formulation of innovative solutions, development of numerical tools and deep understanding of the physical ocean, to optimize the construction and operation in ports, with the primary aim of adjusting costs, maximize safety of the workforce, and expand efficient working windows. Port activity worldwide has the need to increase the future movement of goods, tackle ever larger ships, expand the discharge areas and maneuver, and implement better and more secure computers. This makes port works projecting increasingly large in size, to move toward outer coastal areas, and therefore exposure to the action is complex, variable, and severe environmental conditions.

This means that there is a rethink in the way of planning the construction process of new port infrastructure, and traditional management in the daily operation of existing infrastructure. Therefore, the builder / manager must understand and manage port processes increasingly complex and costly, in relation to the movement of materials and machinery management on site and must prioritize in setting thresholds for optimal safety staff and labor. Thus, the IH Cantabria at the service manager / constructor port an operational methodology, adapted for the daily management of activities related to the work and operation of seaports, through innovative design tools and algorithms to solve and optimize manage from a predictive standpoint, the various problems inherent in this branch of engineering.

Durante la última década, el IH Cantabria ha desarrollado una serie de metodologías pioneras para generar bases de datos históricas Océano-Meteorológicas, tanto a escala global como a escalas regionales y locales. En concreto, para las costas españolas, se cuenta con la reconstrucción histórica de series horarias de viento de alta resolución, oleaje propagado, onda larga, nivel del mar y corrientes de más de 60 años de datos homogéneos, validados y/o calibrados con información instrumental.

Además también se dispone de proyecciones de clima marítimo realizadas con distintos escenarios de cambio climático hasta el año 2100. Efectivamente, IH Cantabria lleva años trabajando en el desarrollo de metodologías que permitan analizar y evaluar los efectos del cambio climático en las zonas costeras. Desde que en 2003 la Oficina Española de Cambio Climático encargara a IH el estudio del cambio climático en la costa, han sido numerosos los proyectos que se han ido sucediendo al respecto, permitiéndo adquirir una amplia experiencia y pericia en este campo.

Los asentamientos urbanos y su desarrollo en las zonas costeras han dado lugar a construcciones que hoy en día se ven afectadas por los impactos del cambio climático. Puertos comerciales, deportivos o pesqueros, vías de comunicación o frentes marítimos sufren los efectos de un clima cambiante. Esto hace necesaria la introducción del estudio del cambio climático en cada proyecto de puertos e infraestructuras. IH Cantabria proporciona, por tanto, una solución integral al diseño de infraestructuras marítimas.

Over the last 20 years IH Cantabria has been developing full-scale monitoring systems of coastal structures (natural and/or artificial) with three objectives :

  • the development of new design technologies based on modeling without scale effects,
  • maintenance of early warning and monitoring systems
  • monitoring of the risk evolution of real structures throughout their life-span.

Using both commercial technologies (GPS, doppler anemometry, buoys accelerometer, pressure and kinematic sensors, remote sensing, etc.) as well as measurement techniques developed ad hoc, IH has accumulated extensive experience in several fields such as: monitoring of breakwaters other port structures, measuring of coastal met-ocean variables,  follow-up of sedimentary process on beaches and estuaries, dynamics of floating objects , etc . Real knowledge on the behaviour of coastal structures represents the final step of the design process and optimization, and complements the theoretical,  numerical and experimental work carried out to scale.

IH Cantabria is actively  developing of tools and methodologies applied to the environmental management of port systems. Many of the efforts of recent years have been based upon the principles established by the European legislation on water quality. In line with these principles, IH Cantabria addresses three major challenges:

  • The adaptation of the generic goals of protection and improvement of aquatic systems to the uniqueness of a port environment by establishing the ROM 5.1

  • The implementation of management models in different geographical contrasted both statewide (Santander, Huelva, Cadiz, Tarragona, Santa Cruz de Tenerife, etc.) And European (UK, Ireland, Portugal, France);
  • The involvement of the business sector for technology transfer and innovation, by creating a discussion group framed within the PROTECMA technology platform.
