Point Capacitance

Capacitance elements:

allow the introduction of concentrated heat capacitance at a point;
are associated with the temperature degree of freedom at a node; and
have a capacitance that can be specified as a function of temperature and/or field variables.

Defining the Capacitance Value

Defining the Capacitance Value

The heat capacitance is associated with the temperature degree of freedom at the node of the element. You specify the capacitance magnitude, $ρ c V$ (density × specific heat × volume). Specify capacitance, not specific heat. You must associate this capacitance with a region of your model.
