# 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.
|
||
|
||
Abaqus/CAE Usage: Property or Interaction module: Special→Inertia→Create: Heat capacitance: select points: Capacitance
