Is OpenFOAM accurate?
OpenFOAM contains a number of solvers [4-7] having different computational properties. Presented in a tabular form solutions [8] have high accuracy and for many years are used for test- ing the computational properties of numerical methods.
How good is SimScale?
SimScale is straight-forward to use even for someone with no previous experience in computational fluid dynamics. The work-flow is intuitive, there is lots of good documentation that get you up to speed quickly. There is also amazing support available through the user forum and the very helpful SimScale staff.
What is CFD analysis used for?
Using CFD, you are able to analyze complex problems involving fluid-fluid, fluid-solid or fluid-gas interaction. Engineering fields where CFD analyses are frequently used are for example aerodynamics and hydrodynamics, where quantities such as lift and drag or field properties as pressures and velocities are obtained.
Is SimScale open source?
SimScale is based on cutting-edge open source solver technology currently being used by leading companies, in a large number of industries with different requirements, such as automotive, aerospace, process technology, and power generation.
Does SimScale use OpenFOAM?
SimScale is based on cutting-edge open source solver technology, including OpenFOAM, which is currently used by leading companies in a large number of industries such as automotive (BMW, Ford, Volkswagen), aerospace, (Airbus), process technology (Siemens), and power generation (General Electric).
Is SimScale better than Ansys?
In summary, Simscale is as efficient as my previous tools (and much more efficient than the Proe/Ansys combination) , more capable, and lot cheaper. I can turn out better products because I can perform more robust analysis upfront, I can do this as quickly as before, and it cost me less money.
Is SimScale easy to use?
SimScale was extremely easy to use, had a nice user interface, and for my purposes, was free. I liked that it was web-based because I didn’t have to use my computing power on my machine. Good software that do not required powerful computer as it is based on the cloud.
How do you analyze CFD results?
CFD Analysis Process
- Forumulate the Flow Problem.
- Model the Geometry and Flow Domain.
- Establish the Boundary and Initial Conditions.
- Generate the Grid.
- Establish the Simulation Strategy.
- Establish the Input Parameters and Files.
- Perform the Simulation.
- Monitor the Simulation for Completion.
What level of accuracy is required from a CFD analysis?
The level of accuracy required from a CFD analysis depends on the desired use of the results. A conceptual design effort may be content with general shock structure information, whereas a detailed design may require accurate determination of the pressure recovery. Each quantity to be determined generally has its own accuracy requirement.
How do I get a CFD simulation to be creditable?
Credibility is obtained by demonstrating acceptable levels of uncertainty and error. A discussion of the uncertainties and errors in CFD simulations is provided on the page entitled Uncertainty and Error in CFD Simulations.
What are the three levels of CFD design and analysis?
The application of CFD for design and analysis may be catagorized into three levels according to increased levels of required accuracy: 1) provide qualitative information , 2) provide incremental quantities, and 3) provide absolute quantities. This discussion follows the ideas of Benek et al.
Is there an error band for the CFD simulation?
The accuracy observed from the CFD simulation varies according to the character of the quantity, and so, it is not possible to state an accuracy or error band that applies to all quantities obtained from the CFD simulation. The verification methods discussed below regarding a grid convergence study will provide the error band for the calculations.
