Dear Bernd, Recently I try to simulate one solidification process with which the dendritic growth is expected. However, results show planar growth. I tried to modify the following parameters: Smaller grid spacing: 0.01 μm Different kinetic coefficients: 0.1, 1, 5, 10 Smaller interval for updating di...

Hi, I want to simulate the solidification process of Al with two solid phases. I prepared the GES file from thermal-cal that contains LIQUID, FCC L12, DIAMOND_A4 and MG2SI_C1 phases. It runs without error when I specify the solid phases as FCC L12 and MG2SI_C1, but I got errors when I try to change ...

Dear Bernd, Thank you so much for the suggestion! We increased the spacing to be 0.07 \mu m and the interface energy to be 1.62E-5 J/cm 2 , as shown below. # Phase interaction data # ====================== # # Data for phase interaction 0 / 1: # --------------------------------- # Simulation of inte...

Dear all, Hi! Recently I try to simulate the dendrite formation process with high cooling rates (10 6 K/s) and high temperature gradients (10 5 K/cm). In the beginning, I used grid spacing 0.07 \text{\mu m} and found the driving force of the dendrite tip fluctuates a lot during the continuous dendri...

Dear all, In order to collect data statistically, I set the following parameters in the driving file under the tag "Phase interaction data". # 'DeltaG' options: default # avg ...[] max ...[J/cm^3] smooth ...[Deg] noise ...[J/cm^3] offset ...[J/cm^3] avg 0.90 max 200.00 noise 1.00 Then I keep all par...
