Dear All,

Why we need to take C = 10^5 for simulating the melting phenomena? I have gone with the lower values of C=10 ^4 also but found nothing changes.

If you have a look in the Theory Guide it's covered there. Quickest way to access is to open the Solidification model panel and click on the Help button.

Hello,

Are you talking about Cp? Can you please let us know how you found this value? Did you see this in an example video or tutorial?

About you model, please share a few more details about your model so we understand the problem you are working on.

Thank you.

Best Regards,

Karthik

For the Mushy Zone Parameter, values between 10e4 and 10e7 are recommended for most computations. The higher the value of the Mushy Zone Parameter, the steeper the damping curve becomes, and the faster the velocity drops to zero as the material solidifies. Very large values may cause the solution to oscillate as control volumes alternately solidify and melt with minor perturbations in liquid volume fraction. For more details, please look into the theory guide how the Mushy Zone Parameter impacts the source term.
