![]() This is a software that allows us to create models and mesh it for generating grids. So, a user can use it readily to get quantitative data at a particular point.Ĭlarification: ICEM stands for Integrated Computer Engineering and Manufacturing. Which plot will you choose if you want your users to read quantitative data from your data visualization?Ĭlarification: xy plot shows the quantitative variation of a dependent variable with some independent variable. It was originally named as FOAM when created by Henry Weller in the late 1980s.ĩ. This can simulate fluid flow, heat and mass transfer, chemical reactions, combustion, etc.Ĭlarification: OpenFOAM stands for open-source Field Operation and Manipulation. When was the first commercial CFD package released?Ĭlarification: PHOENICS is the first commercial CFD package released in the year 1981. We employ a projective technique that takes advantage of the expanded programmability of the latest 3D graphics hardware. Our renderer is interactive and accurately integrates light intensity an order of magnitude faster than previous methods. To represent its direction and magnitude, we can use the vector plot.ħ. In this paper, we describe an unstructured mesh volume renderer. Velocity is the directional flow property of a fluid. Which of the following properties will need a plot like this?Ĭlarification: The given plot is a vector plot. TGrid and ParaView are for pre-processing and post-processing respectively.Ħ. CFD Users Reap Unstructured Grid 10 Spring 2004 Wright Cycles. Some of the other open source software are CF元D, Typhon, OVERFLOW, and Wind-US. will be evaluated for remote visualization potential are Presto, ParaView, and Fieldview. It allows us to develop customized solvers. ![]() Which one is an open source CFD solver tool?Ĭlarification: OpenFOAM is an open source CFD toolbox based on C++. Therefore, point 2 has the highest acceleration.ĥ. Point 2 has lines very close to each other. In a contour plot, the points with high gradient are represented by close lines. Which of these points has the highest acceleration?Ĭlarification: High acceleration means highly varying velocity. ![]() The following plot represents flow velocity. From ANSYS Fluent 12.0, we get adaptive meshing.Ĥ. This was not possible in earlier versions. Complete CFD simulation setup is done in TCFD GUI in ParaView. Is adaptive meshing possible in current CFD packages? If yes, which software offers it?Ĭlarification: Adaptive meshing allows to change or refine mesh during the solution of the problem. An unstructured viscous computational mesh was constructed with Pointwise on the Potsdam. Vector plots display vector quantities at discrete grid points. xy plots show the variation of a flow property with respect to an independent variable. Which of these plots are irrelevant to CFD post-processing?Ĭlarification: Contour plots give a global view of the variation in flow properties. FieldView is a data handling and visualizing tool that can be used for CFD post-processing.Ģ. ![]() Which one is a post-processing Software?Ĭlarification: FieldView is a CFD post-processing software. Lastly, several mesh quality metrics are examined.Computational Fluid Dynamics Multiple Choice Questions on “Simple CFD Techniques – CFD Softwares”.ġ. The volume mesh is generated using T-Rex, our unstructured viscous meshing algorithm, which extrudes stacks of hexahedra and prisms that smoothly transition to an isotropic tetrahedral farfield. The same shape creation utilities are then used to define a source that provides off-body volumetric grid refinement to help track flow features of interest. Post processing is performed in ParaView, with synchronization necessary. Farfield boundaries are generated using automated shape creation utilities. tetrahedral, unstructured overset assemblies, with improvements for dynamic. Starting with a geometry model of an aircraft, you’ll see the entire meshing process beginning with the generation of a quad-dominant surface mesh that is clustered to regions of high surface curvature.
