acceptable range of numerical (cfd) error

m zahid · July 28, 2015, 10:00

hi, various types of equations are available for error calculations such as % difference, RMSE or MSE etc, but no body mentioned the acceptable range of the error, for example 20% error is acceptable w.r.t experimental data or less or more.

if any body know about the acceptable range of the error in numerical simulations . please share knowledge with reference.
thanks

i have heard that 20% error in acceptable in CFD , but i don't know the reference.
