What software is better? Or what software is faster? Are the questions that many have asked, ANSYS CFX or ANSYS FLUENT, well it is difficult to say that one is better than another, or that one is always faster than another.
In this Post we have developed a simulation of a simple thermal analysis testing both softwares for the same mesh and we have obtained the following results:
Solution in 24 iterations
Computed time: 12 seconds
Solution in 3 iterations
Computed time: 3 seconds
Although in this case, ANSYS FLUENT was faster, we can not say that will always be so. It is possible that in other conditions or in other types of simulations the opposite happens.
We invite you to make your own tests and comment your results, you can also try other software.
