If I use 10 cells and 10 cm together with a stretching lets say 2
All cells are initially 1 cm each. Will the smallest cell be 1/2 cm or is it calculated in some other way? Thx R |

It is quite clearly explained in the user guide I think: http://www.openfoam.com/docs/user/bl...hp#x25-1440137

We talked it over here and assumed they are using some kind of numerical summation
L = sum(n=0,N-1)x(1+n/(N-1)) where in the end we get x = 2L/3N based on some kind of average in the middle |
