different mesh size but same answer

Theor APPLIE · July 30, 2017, 06:20

same domain
but refinement mesh size 2 million ; 4 millions ; 6 million ; 8 million
still get same answer for coefficients
please help me

Without knowing more about your domain or simulation in general or what you consider the "same", it sounds like your domain is "mesh independent".

I'd agree with lcarasik.
Additional remark: have you heard of grid convergence index?
If not: have a look into the internet with your favorite search engine.

Cheers
