Detailed Description

template<typename number>
class MeltPoolDG::Heat::ApparentCapacity< number >

Apparent capacity model for latent heat release/absorption during phase change.

This class evaluates the additional heat capacity contribution used in the apparent capacity method. The latent heat is distributed over the mushy zone according to the selected apparent-capacity profile.

The input argument is the solid fraction \(f_s\), where \(f_s = 1\) denotes fully solid material and \(f_s = 0\) denotes fully liquid material.

Template Parameters

number

Scalar number type.
