iconCFD 2.1.1 introduces full support for new species transport solvers and accompanying models and boundary conditions:

– speciesTransportFoam is a transient species solver using a pre-calculated steady-state flow field.
– buoyantBoussinesqSpeciePimpleFoam computes a transient or pseudo-transient, incompressible, turbulent, buoyancy-driven flow along with a species transport solution.

Both solvers are capable of simulating the transport of multiple species. Two new dictionaries have been added:

– speciesTransportProperties: defines the necessary physical properties of the different species (i.e.: density, mass diffusion coefficients …).
– speciesSourceProperties: enables time dependant injection of species in specific regions of the simulation domain.

A new inlet boundary condition is available for simulating the recirculation from outlets to inlets (time delays, specific specie filters, additional sources). This can enable for example the simulation of building and aircraft ventilation systems.

Set-up of specie source in iconCFD GUI

With an additional feature in the fieldProcess function object the user can calculate and output the species concentrations in different units (kg/m3, ppm, …).

The iconCFD GUI allows full set-up of speciesTransportFoam and buoyantBoussinesqSpeciePimpleFoam cases, using the recirculation boundary condition, volumetric specie sources, and species transport properties.

Some example applications are simulating the dispersion of smoke, gases or pathogens in buildings and ventilation systems, the mixing of gases or fluids in industrial processes…

iconCFD 2.1.1 will soon be available. You will be informed in a separate email.

Due to an error by the Conference Hotel it is now necessary ICON, host of the Open Source CFD International Conference, change the dates of the conference, taking place in London. The new dates are now Monday 29th October and Tuesday 30th October, 2012.

The venue remains unchanged:

The Tower,
St Katharine’s Way,
London E1W 1LD
United Kingdom

To take advantage of the Early Bird discount, please click here. Offer ends 29th June 2012.

Abstracts are invited for a broad range of topics and should aim to highlight validated methods and breakthrough technologies. Works should demonstrate how adoption of open source CFD software is moving CAE process and business forward.

The following types of participation are all available at the event:

– Oral (Slides) Presentation + Written Paper;
– Oral (Slides) Presentation only;
– Poster Presentation + Written Paper;
– Poster Presentation only.

The paper submission deadline is 15 June 2012 and a submission form is provided at opensourceCFD.com.

We look forward to seeing you in London.

ICON Technology & Process Consulting Ltd. has formed a sales alliance with Dacolt to promote and support its CFD service, ICON FOAMpro in the Netherlands, Belgium and Luxemburg. ICON FOAMpro provides first class open source-based CFD solver and meshing tools, combined with industrial support embedded in a professional environment.

As a result of this partnership, Dacolt, a CFD consulting company which specialised in Combustion Modelling, will promote and provide support of ICON FOAMpro for Benelux customers. Furthermore, it will carry out CFD consulting business using ICON FOAMpro. ICON will back up the service providing training resources and offer its expertise where needed.

David Green, Commercial Director at ICON, said: “We are delighted to be working with Dacolt. Our organisations share similar values in best practice and customer service, enabling us to offer customers in the Benelux a compelling proposition. We welcome partnerships like these to better meet the needs of our customers in the local markets.”

About Dacolt

Dacolt offers software and services for CFD (Computational Fluid Dynamics) modelling of industrial combustion applications, by providing innovative tools and expertise to support its customers in realising their fuel efficiency and pollutant emissions design goals.

ICON, editors of ICON FOAMpro and experts in Open Source CFD technology and Dacolt, editors of Tabkin and experts in combustion modelling with CFD, have collaborated in the preparation and presentation of a three day training course in Combustion Modelling using OpenFOAM^® technology.

The three day course covers the following topics:

Introduction to combustion modelling with CFD
Non pre-mixed combustion with reactingFoam solver
Pre-mixed combustion with XiFoam solver

An additional training day, An Introduction to OpenFOAM^®, can be added upon request. This training course can also be given on-site.

The next training course is scheduled for June 20-22 in Maastricht, the Netherlands. For more details and to register, visit our training page.

In addition to the ability to create face zones in the volume mesh from STL or NASTRAN surfaces, iconCFD Mesh is now capable of splitting up face zones into two-sided internal patches enabling the user to create baffles of the following types:

– Face zones (a one-sided set of internal faces)
– Internal coupled cyclic patches which can be used for internal jump boundary conditions
– Two zero-thickness uncoupled patches, allowing separate boundary conditions on each side

Surface normals of different baffle types (left: face zone; centre: internal cyclic patch; right: two patches)

As part of the development advanced methods for snapping and creating surface layers were introduced to iconCFD Mesh.

– Feature line snapping is now also enabled for face zones and other baffle types.
– Boundary layers do not collapse when intersecting face zones any more. Now the mesher grows the layers up the baffles (even if they are curved) and assigns the appropriate side faces to the baffle patch.
– Layer growth up non-planar surfaces has been implemented as well as an advanced treatment for layers growing up concave corners. Both these features also increase the quality of the boundary layers growing up inlet, outlet and symmetry patches.

Automatic meshing of baffle surfaces was implemented in iconCFD Mesh for the purpose of increasing the flexibility of face zone usage, directly creating internal jump and cyclic boundaries as well as zero thickness walls with each side on a separate patch, while increasing mesh quality and surface layer coverage.
