Comments about OpenFOAM as a Alternative to ANSYS Fluent
Almost everyone thinks OpenFOAM is a great ANSYS Fluent alternative.
Guest
most powerful alternative but unfortunately it has a steep learning curve and is time consuming to work with even after learning. it will be the best if it has a graphical user interface (GUI).
