Available Elements for Thermal Analysis

The ANSYS and ANSYS Professional programs include about 40 elements

(described below) to help you perform steady-state thermal analyses.

For detailed information about the elements, consult the

Element

Reference

. That manual organizes element descriptions in numeric order,

starting with element

LINK1

.

Element names are shown in uppercase. All elements apply to both

steady-state

and

transient

thermal

analyses.
