Ansys CFX

Brief Overview of Ansys CFX Software

ANSYS CFX and Ansys Fluent Software Application from Ansys Singapore are two CFD Simulation solvers were Independently independently and have Quite a number of things in common, However, they also have some significant differences.
Both Ansys Fluent Software Application & the other Ansys Fluid Flow Simulation Program, Ansys CFX Software Platform are control-volume based for high Results accuracy and rely heavily on a pressure-based solution Approach for Wide Engineering Application.
They differ Largely in the Method they integrate the fluid flow Mechanics equations and in their equation solution strategies.
The ANSYS CFX Physics solver uses finite elements (cell vertex numerics), similar to those Utilized in Engineering mechanical Simulation analysis, to discretize the domain.
In contrast, the ANSYS Fluent Software Application solver, like those used by the Popular Ansys Fluent Student Version uses finite volumes (Element cell centered numerics).
ANSYS CFX Software Program Targets on one Method to solve the governing equations of motion (coupled algebraic multigrid), while the ANSYS Fluent Flow Simulation Software Program product offers Many solution approaches (density-, segregated- and coupled-pressure-based methods).
In Fact, Both Approaches works Relatively Well Via Finite Volume Methods.
Our Engineering Simulation Team at BroadTech Engineering Have gone through Ansys Workbench Fluent Software Program quite a number of times in a Recent couple of years while Focusing on Actual Customer Engineering projects.
For this to be Fully understood and Appreciated, you must go through these User Defined Function Source codes Yourself when you Initially buy Ansys Fluent.

In the Ansys Fluent Gambit Software Application, the element is of the volume of control.
This means the number of control volumes is equal to the number of Mesh Cell elements (Cell-Centered) in Ansys CFD Fluent Commercial Version and Ansys Fluent Student Version.
Whereas, on the other hand in the Ansys CFX, the volume of the control is assembled around the Mesh Cell nodes (Cell Vertex), where each Mesh Cell element is divided into sub Physical volumes.
As a Consequence, the Flow flux through each Surface is based on the nodal values of the Cell element. Once subdomain contributions are evaluated, the Mesh nodes Corresponding for each sub-volume around itself and the real volume of the control is assembled.
In Aspect of Meshing grid quality, Ansys CFX is Generally more permissive compared to Ansys Fluent Student.

Frequently Asked Questions About Ansys CFX Software


1. What are the Main differences between Ansys CFX and Ansys Fluent Software? 

Listed Below are some of the Key differences that come to mind right When Comparing the two World Class CFD solvers.
2D Meshing Capability
– Ansys CFX Software Applications cannot handle an Actual 2D mesh. It can Process a pseudo-2D mesh which would Have to be a 1 element thickness 3 Dimensional Meshing. Whereas Ansys Fluent Software Solving Solutions can handle 2D Meshing with no problems.
Types of Compatible Mesh Element Topologies (eg. Polyhedral, Cutcell, Tetra, Hexa)
Ansys CFD Fluent Software uses a cell-centered Method while Ansys CFX Software Solutions Utilize a Vertex-Centric Meshing approach.
The Main point being is, Ansys Fluent Simulation Software is Suitable For handling and Solve polyhedral Meshing and cutcell meshes, while Ansys CFX Software sticks to just the Conventional Tetra and Hexa mesh Element topologies.
– CEL (CFX Expression Language) is also used In-conjunction with CFD-Post Processing. So it’s Much easier to define Mathematical equations and Observe them during your CAE Simulation Solving with Ansys CFX Software.
Ansys Fluent Meshing Software needs manually User Defined Functions UDF for User-Specific customization which can Complex things for New Beginners.
Ansys Workbench Fluent Software has Integrated post-processing capabilities of its own while Ansys CFX Software Application needs a Separate Post-Processing Add-on.

Active Adaptive Meshing Capability

– Mesh Adaptive capabilities are Noticeably Poorer in Ansys CFX Software compared to Ansys Fluent Student Version Software. In Ansys CFX Software, which is available in the Ansys CFD Download section, the “Adaptive meshing is available for single domains with no GGI interfaces and limited physics.

Aggressive Software Update Schedule from Ansys Software Developers

– The World Class Ansys Fluent Software is continuously worked upon by the Software developer engineers at Ansys R&D and there is a significant improvement made and Added with every new Software Version release.
Ansys CFX Software & Ansys CFD Meshing Software definitely lacks the focus that Fluent Software and Fluent Student gets from the developers, in my opinion.

GPU Acceleration

– Engineering Simulation Process acceleration with a GPU Process is Technically possible in Ansys Fluent CFD Software, while it doesn’t Improve Engineering Simulation Performed Using Ansys CFX Software.

2. Are Ansys CFX & Ansys Fluent Software each used for Solving any specific Category of Engineering problems?

If yes, why are those problems used for Fluent?

Ansys Fluent Software and Ansys Fluent CFX Software are both equally good CFD Simulation solvers in terms of Simulation Solving Performance and Functionally.
Often the Ansys Simulation Software Application Preference primarily Rely on the Real life physics of the Fluid flow being Studied, the user’s prior familiarity with the Simulation solver as well as the Quoted Ansys Price Offered by the channel Reseller.
Several existing End users who only buy Ansys Fluent Software, they Usually have never Really tried the Ansys CFX Fluid Simulation software.
Each CFD Software Has it Own Advantages & Specific Applications it is Suitable For
Similar to Ansys Discovery Live Both the Engineering Simulation solvers can handle most of the Common Fluid flow Mechanics with some Negligible Simulation limitations for both Software Platforms.
It has been Largely believing that Turbomachinery is A Area of Engineering Simulation where Ansys CFX Software has been proving its worth as an Ansys CFD Post Processing Software Tool, compared to other CFD Software, such as Ansys Discovery Ultimate or Ansys Discovery Aim.
Ansys Fluent Software, On the other Hand, is Generally Chosen for high Mach number Fluid flows (supersonic and hypersonic flows).
