solidification of Al-alloy (seed_density)

Dear Bernd,
Best wishes for you.
I have used MICRESS to study the structure and composition distribution of isothermally solidified single-grain and multi-grain aluminum alloys. But when I studied the non-isothermal polycrystalline grains, I encountered difficulties: Under the condition of no latent heat, the density of the grains meets my requirements (see Figure 1), but under the condition of latent heat, no matter how I adjust the crystal nucleus density as well as the nucleation shielding time, the growth of crystal grains is only concentrated in the upper left corner (see Figure 2). So I hope to have your guidance.
Bless you again.
