CFD.NINJA – ANSYS CFD
CFD.NINJA is a group founded in 2014, since then we have been dedicated to the research and dissemination of topics related to Computational Fluid Dynamics (CFD) for which we use various CFD simulation software such as ANSYS FLUENT, ANSYS CFX, ANSYS MESHING, ANSYS ICEM CFD, OpenFoam, DesignModeler, SpaceClaim, Rocky DEM, Autodesk Inventor, Ensight, etc.
We invite you to subscribe to our youtube channel, Facebook page, Twitter and Instagram where we share monthly ANSYS CFD tutorials. Eventually, we do a giveaway for CFD books and gift cards where our subscribers participate.
More than 150 Free Tutorials using Ansys Fluent, Ansys CFX, Ansys Meshing, DesignModeler, SpaceClaim, Autodesk Inventor, ICEM CFD.

Computational fluid dynamics (CFD) is a tool with amazing flexibility, accuracy and breadth of application. But serious CFD, the kind that provides insights to help you optimize your designs, can be out of reach unless you choose your software carefully. To get serious CFD results, you need serious software. Ansys CFD goes beyond qualitative results to deliver accurate quantitative predictions of fluid interactions and trade-offs. These insights reveal unexpected opportunities for your product — opportunities that even experienced engineering analysts can miss.
Ansys Fluent Tutorials
Source: Ansys
Fluent software contains the broad, physical modeling capabilities needed to model flow, turbulence, heat transfer and reactions for industrial applications. These range from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing and from clean room design to wastewater treatment plants. Fluent spans an expansive range, including special models, with capabilities to model in-cylinder combustion, aero-acoustics, turbomachinery and multiphase systems.

Ansys CFX is a high-performance computational fluid dynamics (CFD) software tool that delivers reliable and accurate solutions quickly and robustly across a wide range of CFD and multiphysics applications. CFX is recognized for its outstanding accuracy, robustness and speed when simulating turbomachinery, such as pumps, fans, compressors and gas and hydraulic turbines.
BladeGen + Turbogrid + Ansys CFX – Centrifugal Pump
Source: MichaelSmithEngineers A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out...
Ansys CFX – Compressible Flow
Source: Ansys Compressibility effects are encountered in gas flows at high velocity and/or in which there are large pressure variations. When the flow velocity approaches or exceeds the speed of sound of the gas or when the pressure change in the system ( ) is large,...

Ansys Meshing Tutorials
Source: Ansys
Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain. The mesh influences the accuracy, convergence and speed of the simulation. Furthermore, since meshing typically consumes a significant portion of the time it takes to get simulation results, the better and more automated the meshing tools, the faster and more accurate the solution.
Ansys provides general purpose, high-performance, automated, intelligent meshing software which produces the most appropriate mesh for accurate, efficient multiphysics solutions — from easy, automatic meshing to highly crafted mesh. Methods available cover the meshing spectrum of high-order to linear elements and fast tetrahedral and polyhedral to high-quality hexahedral and Mosaic. Smart defaults are built into the software to make meshing a painless and intuitive task delivering the required resolution to capture solution gradients properly for dependable results.
Ansys Meshing – Body of Influence
