what are space discretization errors and time discretization errors?
 

I am a beginner in CFD. Please explain me the following words:

The level of grid dependence of results, and space discretization errors.
The level of convergence in time , and time discretization errors.
The method’s iterative convergence for the cases presented.

How to prove and how to determine them. Sorry in my bad English.

Thank for your suggestion. :confused::confused:
