INERTIA

Contents: Description, Units - Change Card, Usage, Examples, Related Variables Description This variable is the thermal inertia of the upper material. Units - Change Card Index Units: J m-2 s-1/2 K-1 Change Card Index: 1 3 Usage Layer 1 is the atmosphere. This material property begins at layer 2 and continues until it is switched at the layer set by the variable "IC". Example Value 1000
