Hi, everyone.

I already asked about LES, got some helpful answers.
But unfortunately, I am still have some questions.
Please help me!

1. Is the implicit filtering same as averaging over grid volume?
If so, how does it different from RANS?
If not, what is the implicit filtering?

2. What is the difference between implicit and explicit filtering?

Thank you for your reading!
