Seed density model: determine active nucleants?
Posted: Thu Mar 11, 2021 2:49 pm
Hello all
I run a directional solidification model with an initial grain at the bottom. I simulate one solid phase. Furthermore, I allow an additional nucleation from the liquid phase. For this I use the seed density model with 10 classes and give verbose output for nucleation. Now I would like to know how much of each class of nucleants are active.
As far as I know there is no specific nucleation output but a nucleation verbose. The command "nucleation verbose" gives me the following output:
Seed number 4 set at time t = 0.14000E-02 s
-------------------------------------------
in the bulk
Phase: 1 (FCC_L12)
Seed type: 1 (9: 2/2) --> Does the number "9" refer to class "9"? What does the 2/2 mean? 2 nucleants of this class were activated?
Local temperature = 919.70 K
Undercooling = 5.7853 K
Grain number = 5
In order to calculate the number of active nucleants I would have to search through the scr-output and count the occurence of the number in the brakets. Is that correct? Or is there another approach to this
Thanks for clarifying and your help
