Problem description

A simple transient heat transfer analysis of a heat link constructed with DC1D3 elements is considered in Abaqus/Standard. In Abaqus/Explicit CPE4RT elements are used to model the heat link. The temperature at one end of the link is fixed, while a flux is applied to the other end. The conductivity and the specific heat of the material comprising the heat link vary with prescribed values of a field variable (FV). The value of this field variable is altered with time.

In both Abaqus/Standard and Abaqus/Explicit a transient analysis is conducted. The total simulation time is 6.

Results and discussion

The nodal temperatures of the link confirm that the thermal properties of the material do, indeed, depend on the field variable. The actual values of the material parameters as a function of the field variable are, therefore, correct, since the temperatures were calculated from these parameters by Abaqus.
