difference between CFX and fluent
hi can anyone tell me whats the difference between CFX and fluent...which is more advanced which is more user friendly....which is better to can one comment one the results obtained from CFX and fluent....

thanks Rashmi

Re: difference between CFX and fluent
Search the archives, this has been discussed ad nauseam before. The summary is that it is horses for courses, each product has its strengths and weaknesses. I like both.

Re: difference between CFX and fluent
this pretty much falls into the, how big should my cell size be, which turbulence model is best, how long is a piece of string....idiot question category

Re: difference between CFX and fluent
in some applications like supersonic/hypersonic flows....fluent is having advantage over cfx..because of its coupled solver (where energy-flow coupling is done directly); i dont think cfx is having this capability. Personally i felt fluent gives faster convergence for the same setup conditions for a problem....if u dig up...many are there.... finally...i can conclude that fluent is better than cfx.

Re: difference between CFX and fluent
thanks for ur replies i want difference betwenn CFX and fluent for solving multiphase flows........

Re: difference between CFX and fluent
Fluent have the upper hand in multiphase flow especially when it involving PBM. CFX has it PBM too but not as advance as Fluent.

difference between cfx and fluent
ANSYS FLUENTand ANSYS CFX two solvers were developed independently and have a number of things in common, but they also have some significant differences. Both are control-volume based for high accuracy and rely heavily on a pressure-based solution technique for broad applicability. They differ mainly in the way they integrate the fluid flow equations and in their equation solution strategies.The ANSYS CFX solver uses finite elements (cell vertex numerics), similar to those used in mechanical analysis, to discretize the domain. In contrast, the ANSYS FLUENT solver uses finite volumes (cell centered numerics).ANSYS CFX software focuses on one approach to solve the governing equations of motion (coupled algebraic multigrid), while the ANSYS FLUENT product offers several solution approaches (density-, segregated- and coupled-pressure-based methods):):D

Fluent FDM without mass conservation oder FEM?
edit: deleted and opened a new threat, since it is a different question I have

I am simulating mixing of two fluids ( both of them are water with identical physical properties) in a 3D T-shaped micromixer. which software do you recommend for this simulation (CFX or Fluent)?

Best regard

Dear Member,

As your Flow problem of multi phase with simple geometry and static condition to get faster convergence and user friendly for beginner of CFD CFX is best for you.

Note : If you particularly looking into pressure as output monitor plot then going for fluent with PISO and pressure based solver with second order upwind will have higher accuracy in your solution compare to CFX.
