THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below.
User who did this - Bernd Flemisch (bernd) Attached to Project - DuMuX Summary - Improve terminology in Newton output / parameters Task Type - Feature Request Category - General Status - New Assigned To - Bernd Flemisch Operating System - Unspecified Severity - Low Priority - Normal Reported Version - SVN Due in Version - 2.7 Due Date - Undecided Details - Our Newton offers two stopping criteria: 1. max_i | u_new,i - u_old,i | / | u_i | < tol_r This is our standard one and we call it "relative criterion" with parameters "EnableRelativeCriterion" and "RelTolerance". The term max_i | u_new,i - u_old,i | / | u_i | is indicated as "relative error" in the output. 2. | res(u_new) | / | res(u_init) | < tol_a We call this one "absolute criterion" with parameters "EnableAbsoluteCriterion" and "AbsTolerance". The term | res(u_new) | / | res(u_init) | is indicated as "absolute error" in the output. This terminology is non-standard and misleading. For example, both quantities are not "errors" and both are "relative" in the sense that they are weighted. I could not find a standard terminology. We have to improve at least the output to avoid confusion and will hopefully find something better for the parameter names.
