Ansys CFX vs. Simcenter STAR-CCM+

The simulations obtained are very advanced, showing great results in the movement of fluids in the different states of which it is required to obtain an understanding of their movement dynamics. I obtained impressive and illustrative results of the thermodynamic properties that occur in said flow. Ansys CFX is an easy solution for doing multiple different types of analyses.

A case where you are interested in modeling various physics such as
Aerodynamics,
Hydrodynamics, Heat Transfer & Thermal Management, Multiphase Flow, Fluid-Structure
Interaction (FSI), Combustion & Reacting Flows, Aeroacoustics, Electrochemistry, and Electromagnetics. STARCCM+ is recommended. But if your interest is complex Structural dynamics, durability, or Motion analysis, etc. better to go with other tools.

• The GUI of Ansys CFX is pleasing to the eye and at the same time user friendly, making it a lot easier to identify the required fields.
• The numerical scheme is based on Finite Volume Methods. It supports multi-phase flows with no mass transfer.
• In the Ansys CFX, adaptive networking can be used for GGI interfaces and single domains without restricted physics.

• Meshing is very easy to do in STAR CCM+
• Post-processing results is also very intuitive, making extracting results very enjoyable and easy to use.
• The Advanced rendering options that are available in STAR CCM+ can really help make very well-generated videos that can make the simulation easy to visualize, share with non-technical engineers, and showcase the study done.

• One thing which I think they can do is provide flexibility to the user to modify the stuff inside the black box
• Sometimes the errors can be confusing. The geometry of design and meshing is sometimes troublemaking.

Incentivized

• Maybe a little bit on the automation side and if you want to script something, if you want to automate procedures, that happens through every simulation round that you have. That part could be a little bit cumbersome right now, depending on the operating system that you use.
• Introducing the software on other platforms like Mac OSS.

STAR CCM+ technical support was very quick to respond when a ticket was raised for issues. For support in setting up a test case for the Lagrangian particle tracking technique, a support assist agent was assigned immediately, and after having a detailed discussion, my problem was understood by them, and a suitable test case was shared, which I was able to understand and use to build my case.

It is super easy when it comes to implementing it.

Competitive tools, both Fluent and STARCCM+, but the user interface and ease of learning, along with everything in a single interface, and a wide variety of proven physics capabilities, along with good scalability and automation, made the choice easy for me. Also, the user guide and tutorials available to explore various kinds of Physics capability, and A single license for access to all physics, also made it easy.

• The interface of Ansys CFX is much neater than Ansys Fluent. I found it much easier to define materials and boundaries in Ansys CFX. Also, this will allow me to get much more accurate results compared to a simples Thermal transient analysis

• Time saved in creating a inhouse code, tens and tens of hours.
• Time saved in experimental setup, tens of hours.
• Does add some time in testing to confirm star is doing what you think it's doing, but an overall net gain in productivity.
