I need to ask a question that if i can learn CFD in ANSYS STUDENT version which is free or not?
If there is a completely different software for CFD.
What is ANSYS fluent and from can i download it or buy it?
ANSYS is definitely a reputable program, and I'm pretty sure they have a student account as I have heard of many young people using it. However, if you are considering free softwares, I would consider SimScale. They have a community account and also academic programs.
