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 Fluent Tutorial | Heatsink
A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device's working surface area and the amount of low-temperature fluid that moves across its enlarged surface area. Based on each device's...
Ansys Fluent | Hydraulic Jump
Free surface is the surface of a fluid that is subject to zero parallel shear stress, such as the interface between two homogeneous fluids, for example, liquid water and the air in the Earth's atmosphere. Unlike liquids, gases cannot form a free surface on their...

Ansys CFX Tutorial | Flow through Porous Media
A porous medium is a solid with voids distributed more or less uniformly throughout the bulk of the body. The basic characteristic of this medium is porosity. The bulk porosity Π of a material is defined as the ratio of void volume Vv to body volume V0, Π = Vv/V0....

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.
