Relative Error in dependent Variables

Hi,
I'm working on a model using the Turbulent Flow, k-epsilon module.
The model runs fine and I am then able to look at several different variables (Density, Dynamic Viscosity, Velocity Magnitude, etc.).
How do I get the relative error for these variables based on my solver conditions?
For example if in the log it reports my LinErr is 3.4e-6 how do I then get the error in velocity magnitude?
Thanks

Hi
from my experience, it's by analysing the sensitivity of the response to small changes of critical parameters such as the mesh density or main BC values. You have also the "sensitivity analysis" to perform in a more automated way, these analysis

Good luck
