RELATIVE CHANGES FOR CONVERGENCE STUDY

Post by Andrea_P »

Good Evening,
I would like to study the convergence of my case, but I don't know how I can save the relative changes of the physical variables of interest in order to plot their evolution. I thank you in advance for your answers.
Regards,

Elmers Model manual page 264 shows how you can save data to a file during an analysis.

Hi

You could follow, for example, convergence of temperature with SaveScalars

Code: Select all

  Variable 1 = Temperature
  Operator 1 = Norm
  Operator 2 = nonlinear change
  Operator 3 = nonlinear iter

Of course what ends up in the file depends when you call SaveScalars with respect to the simulation sequence.
