|
|
Determines the general time integration scheme for the pseudo-time integration of the reinitialization equation. |
|
|
|
If an IMEX integration scheme is specified, the integration in pseudo time of the reinitialization is done with an implicit-explicit scheme. This means that the diffusion part is treated with the IMEX integration scheme and the Hamiltonian is treated with the general time integration scheme. When choosing an implicit scheme with A-stability, larger time steps can be chosen, only limited by the stability of the Hamiltonian part. This is done since the diffusion part is the most restrictive part for explicit time integration schemes. If a scheme is set, the time step calculation based on a CFL number assumes an A-stable scheme and only calculates the time step based on the Hamiltonian. |

|
Function type for the apparent capacity method to model latent heat during solidification. constant: apparent capacity is constant between the solidus and liquidus temperature; qlq: apparent capacity is given by a quadratic/quadratic function of temperature between the solidus and liquidus temperature (default); poly4_bell: apparent capacity is given by a bell-shaped quartic polynomial function of temperature between the solidus and liquidus temperature. |

Choose how to interpolate the properties over the interface. sharp: properties jump at heaviside = 0.5; smooth: properties are smeared between the phases proportional to the heaviside (default); consistent_with_evaporation: same as βsmoothβ, but the density is interpolated proportional by the harmonic mean. |

|
Choose how to interpolate the properties over between the liquid and the solid phase. mushy_zone: solid and liquid properties are interpolated between the solidus and liquidus temperature (default); sharp: the solid and liquid properties jump at the melting point, which is set via the solidus temperature. |
