Dear all,

In the Kobayashi phase field model for dendrites, is it possible to modulate the density of the branches please ? I mean if for instance a dendrite is of radius R in 2d, and the dendrite part is modeled by phi=1 and the medium by phi=0. Then is there a possibility to decrease the ratio S/(4 pi R^2) where S is the surface of the snowflake where phi=1 ? So that the dendrite is sparser in branches (or those are thiner) ?

It seems from the article of Kobayashi (Modeling and numerical simulations

of dendritic crystal growth, 1992) that the value of the latent heat changes it, but I'm not sure about that.

Thanks in advance

Joseph
