Hello,
I major in heat storagy of PCM melting process ( solid to liquid phase ). And I have a problem in my field.
Do I need to set the viscosity of the solid material as large as 1e8 Pa*s or just as the same as liquid phase
( 0.024 Pa*s ) ?
But in the sample of CONTINUOUS CASTING, the viscosity of solid Alloy is the same as the liquid one.
Any tips and help will be great. Could you give me a hand ?
Best wishes to you!

Hi,
You need to include the whole domain solid+liquid in a fluid flow physic and assign a domain (solid one) with a viscosity of 10^8 Pa*s and overwrite with an other domaine (liquid one) with 0.024 Pa*s.
These domaines have to be called in the heat transfert with phase change in phase 1 -> solid and phase 2 -> liquid.
Hope it helps
Best regards
