Hi Micress Forum,
How do i find the values of entropy change and Mobility for a directional solidification simulation I've run?
Thanks,
Matthew

Dear Matthew,
I am not sure whether I understand your question correctly: You have performed a MICRESS simulation (with coupling to thermodynamic data), and you want to find out which thermodynamic data (dS, slopes m, ...) have actually been used?
You can find these data in the .log-file: At the moment when a given phase-interaction is initialized, the complete set of linearisation data is written to the .log-file as a block like:
The linearisation parameters of the phases LIQUID/FCC_A1 are:
-----------------------------------------------------------
950.00000 ! T0 [K]
40.376308 ! dG [J/cm**3]
1.1632438 ! dSf+ [J/cm**3K]
1.1141341 ! dSf- [J/cm**3K]
976.52841 ! dH [J/cm3]
3.0050908389271 ! c0(CU)/LIQUID
0.31844845669844 ! c0(CU)/FCC_A1
-6.1950935 ! m(CU)/LIQUID
-56.940818 ! m(CU)/FCC_A1
-6.81472645E-03 ! dcdT(CU)/LIQUID
7.74115873E-04 ! dcdT(CU)/FCC_A1
If you want to monitor how these values change during the simulation, you can have a look into the .TabLin-output, where you can see the same data at later times (always given as one line for each grain-interaction/occurance of linearisation data).
If your question was different, please reformulate it.
