Hi guys ;

I wanna to simulate an static mixer and investigate mixing process ; my question is that which software is useful ; comsol or fluent ?

my other question is that how can i draw geometry with gambit ?( In the standard Lightnin mixer,with an aspect ratio of 1.5,the
semi-elliptica lplates are assembled at 34◦ and146◦ to the flow
axis)

thanks in advance

I'd say Fluent is more powerful as a CFD solver. Gambit is legacy software so I wouldn't recommend it anymore for geometry creation or meshing.

regarding to the simulating software I agree with cdegroot. Fluent has the more power than comsol to simulate the flow.
It seems you are not familiar with Gambit, first, the data you provided is not enough . second, if you have an elementary knowledge about how to use Gambit it is better to start the work and ask your questions during drawing the model. Asking such a general question can't help you and it also will not encourage others to help you.

Thanks

Can I import comsol's mesh in fluent?

I am not sure about that. You may use google search to find your answer quickly or wait for other friends to response.
excuse me

But with Gambit you can still build and mesh whatever you want, and then compute your physics onto your mesh with fluent, or even with another solver (like OpenFOAM for instance).

Yeah, I'm not saying there is something wrong with using Gambit if you already know it. It just sounded like he didn't know how to use it yet, so my point was that you might as well spend your time learning something that isn't already legacy software. Then if you have problems you can get support.

yes you are right, there is no support anymore.
But you can get some here on the forum
