hello friends, i am new to fluent and cfd. please guide me from where should i start my work on ic engine simulation

Start from the fluent GUI, everything is given in logical order or need (from left to right). Look at the menus and try to understand what each is for. Try to gather the answers from manuals, or from other people who have experience with fluent.

Take a very small mesh, say 1000 cells and do some experiments with it. Untill you feel you are comfortable with it.

I will do some tutorials. Although you won't understand it totally it's a good way to get use with fluent iterface.

I would support the use of the Cornell tutorials. I really like these and will devlop some others in time.

One thing that is really important is a willingness to 'stand back' from all the 'button pushing' and ask yourself what does it all mean?

I.e. what was the purpose of xx etc.

That way you will not be too tied to the buttons/interface of fluent but gain a better understanding of the cfd methodology.

Good luck
