# RhoCp(T) law: models

## Introduction

This section deals with the volumetric heat capacity **ρCp(T)** from the point of
view of the Flux models.

## Models

The numerous models provided are presented in the table below.

Volumetric heat capacity ρCp … |
---|

… constant (independent of temperature) |

… linear function of T |

… exponential function of T |

… tabulated function of T |

… combination of a Gaussian function of T and a constant* |

… combination of a Gaussian function of T and an exponential of T* |

Note: * These models, which associate a Gaussian dependence on T to another function of
T, take into account the phase transition of the 2

^{nd}order at the Curie point.Specific models are also provided (see table below). Their mode of use is presented in § Spatial model / user model.

… spatial (ρCp described via spatial formula) |

… user ( ρCp described via user subroutine and personal version) |
