# Isotropic Heat Conduction Properties

These are the properties of the Isotropic Heat Conduction model:

- conductivity f
Matrix thermal conductivity. This keyword is also for Advection-Conduction and and a read-only property for Hydration.

- expansion f
Matrix linear thermal-expansion coefficient. See Thermal-Stress Coupling for further information.

- specific-heat f
Matrix specific heat. This keyword is also for Anisotropic Heat Conduction, Advection-Conduction and a read-only property for Hydration.
