+
+# Overview
+
+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
+
+The heat capacitance is associated with the temperature degree of freedom at the node of the element. You specify the capacitance magnitude, (density × specific heat × volume). Specify capacitance, not specific heat. You must associate this capacitance with a region of your model.
+
+Input File Usage: \*HEATCAP, ELSET=name pcV where the ELSET parameter refers to a set of HEATCAP elements.
