Hi,
I met a question lately, I use interFoam to simulate two phase. But when I run interFoam, The terminal is always wrong.

Courant Number is less than one. I do not know where is wrong. And this problem has been bothering me for a long time. I really hope someone here could help. Thank you.

Maybe my 0 file is wrong, but I dont know where is wrong.

Could someone please help me out this trouble?
