27 Description
28  Use spring analogy - attract neighbouring cells according to the distance
29  of their cell indices.
30 
31  // Maximum jump of cell indices. Is fraction of number of cells
32  maxCo 0.1;
33 
34  // Limit the amount of movement; the fraction maxCo gets decreased
35  // with every iteration.
36  freezeFraction 0.9;
37 
38  // Maximum number of iterations
39  maxIter 1000;
