relationship btw gird size and some coefficients

#1 Unread post by tony1230 »

hi roms friends

Recently i have been thinking about what i mentioned in the subject. It's Kate's post in a earlier thread viewtopic.php?f=31&t=2673&hilit=rho0#p9996 that reminded me this. I have never taken this into practice, but after saw that, i want to know the relationship btw grid size and some related coefficients,say TNU2/4,VISC2/4,AKT_BAK(if refine vertically), etc.

How to adjust those coefficients if we double,treble,..., the grid size. Thumb rules or formulars ?


Tks.

Your recommendations would be appreciated.
