COMSOL or Fluent ?
Hi everyone,

I am new with CFD analysis. I have a few questions about COMSOL and Fluent:

1) What is the difference between COMSOL and Fluent. Do they have the same function?

2) In your opinion, which program will be better for oil and gas industry. ie, i need to deal with sloshing model and flow model.

Thanks in advance for your advice.

Forget COMSOL. This is easy to use for small problems (academic, 2D, etc) but not for realistic cases. You should either consider one of the large suppliers like ANSYS-CFX, Fluent, StarCD.......

Re: COMSOL or Fluent ?
I agree. If you're more in the 'Open source'[1] or more rigorously 'Free software'[2] spirit, I would highly recommend using OpenFoam[3]. I've been a Fluent user for about 3 years now, and I'm making the transition to OpenFoam simply because it offers me more freedom to tweak every aspect in detail.

Is openfoam a software to simulate foam and foaming flows?

Re: COMSOL or Fluent ?
No. If you read the webpage correctly, you'll see that it is a general purpose CFD code that can even do DNS if you want. It has most capabilities already. Interface tracking VOF, Eulerian bubbly flows, etc. etc.

Hi MAC ,

I dont know any thing about C++ (which openfoam is based ) . I want to use the VOF level set method . Do I need to learn C++ in order to use openfoam ? or is it just as like using commercial codes with no GUI ?

if you don't want to developp your own solver, you don't need to learn C++.
Just use solvers which are already available.
