class m_melting.Melting(MeshClass, ElemClass, TracersClass)

Bases: object

Class that contains functions related to the phase transition inside the domain.

add_melt_tracers()

If the temperature in the domain is within a given range below the melting temperature \((T > T_{\rm melt} - dT_{\rm melt\_thresh}\), see T_melt and dT_melt_thresh in m_parameters.py), the number of tracers is checked. If the number of tracers is lower than 10, the tracers are added.

Variables:

  • T_melt – the melting temperature

  • dT_melt_thresh – a threshold for adding or removing tracers when melting

Note

If melting is the only mechanism requiring tracers, the tracers will be used only in the part of the domain where \(T > T_{\rm melt} - dT_{\rm melt\_thresh}\), which saves computation time.

compute_initial_melt(Temp, density)
compute_melting()

Computes the amount of partial melt on the tracer.

Variables:

  • T_melt – melting temperature

  • Lt – latent heat

  • cp() – specific heat defined by m_material_parameters.cp()

delete_melt_tracers()

If the temperature in the domain drops enough below the melting temperature \((T < T_{\rm melt} - dT_{\rm melt\_thresh}\), see T_melt and dT_melt_thresh in m_parameters.py), the tracers are removed.

Variables:

  • T_melt – melting temperature

  • dT_melt_thresh – threshold for adding or removing tracers when melting
