Customized open-source CFD modeling

• Why should you invest into custom tailored model developement?
• In a large variety of applications involving fluid flows, standard models are not 100% accurate. By improving existing models your company or institution will be able to have an extra edge compared to competitors.
• With the implementation, verification and validation of newly impelemented models your company or institution willbe the sole user of the models. By having models implemented via eulerian-solutions e.U. your code will not end up in some future release of any of commercial or non-commercial CFD codes thus giving your company or institution an additional edge compared to your competitors.
• Will you receive the quality you need?
• In order to reassure yourself regarding the quality of work provided, please refer to the section of all open-source CFD publications by József Nagy.

Customized workflow for open-source CFD with OpenFOAM

• Geometry

• Mesh

• Simulation setup

• Simulation

• Results

• Although there are many introductory tutorials available, the first learning curve in OpenFOAM is very steep. You can reduce your initial learning period by investing into a customized workflow for your specific problem setting.
• How can you benefit from a custom CFD simulation workflow?
• Find out how you best create your geometry and how you can import the information into your OpenFOAM simulation.
• Reduce the duration of your CFD project by identifying most dominant settings during meshing.
• Learn best practice inputs to own your mesh.
• Reduce the duration of your CFD project significanty by identifying most important initial and boundary conditions, simulation and numeric settings and collecting them into one master file, which you edit. All other settings can be left untouched.
• Minimize post processing time by setting up scripts to automatically evaluate during runtime your quantities of interest.
• List of workflows provided by eulerian-soltuions e.U. to customers:
• rotary kiln with burners including combustion and radiation modeling
• fire safety simulations
• car park ventilation with jet fans
• atmospheric boundary layer simulation
• dispersion simulation of poisonous gas
• cooling of electronics
• droplet breakup
• fluid-structure interaction modeling in various industrial and medical processes
• modeling of non-Newtonian fluids
• modeling of oceanic flows
• aneurysm modeling
• solar radiation

Automated wrapper application for open-source CFD with OpenFOAM

• The above workflow cannot only be set up as a list of commands for you to follow. eulerian-solutions successfully implemented wrapper applications which automatically set up dictionaries and run the required pre processing tools, simulations and post processing applications.
• How can you benefit from an automated CFD simulation workflow?
• You have a specific process, where the physics does not change between simulations and you use the same set of preprocessing tools over and over again.
• A set of files (one configuration file + your geometry files) is all you will have to specify and the custom tailored wrapper application will do everything else for you.
• You only have to worry about the parameters which matter to your process.
• You don't have to worry about syntax mistakes, as the wrapper application sets up the dictionaries correctly for you.
• Best practice initial and boundary conditions are used, where possible.
• Numeric settings are optimized for your process.
• Minimize post processing time by automatically evaluate during runtime your quantities of interest.

Open-source CFD services

• eulerian-solutions e.U. offers detailed and precise workflow for CFD services:
• A typical CFD project always starts with a custom problem setting of you and your company.
• The problem setting is defined as a set of parameters defining the geometry, the process parameters as well as the quantities, which have to be evaluated.
• Mesh settings with the most suited mesh is generated with the defined geometry.
• All the defined process parameters as well as required numeric settings are selected.
• A set of cases are set up for a possible parameter study.
• Simulations are evaluated and results presented in the form of your choice (report, presentation etc.)
• Optionally models can be validated against results from literature or your own experimental data.
• Optionally new models can be implemented for you and your company. These models will be your own and none of your competitors will have access!

• eulerian-solutions e.U. offers a wide variety of CFD services:
• The following topics are provided in CFD service projects by eulerian-soltuions e.U.
• fire (flame) modeling e.g. burners in industrial kilns
