Coupled thermal-electrical analysis

Coupled thermal-electrical problems:

  • are those in which coupling between the electrical potential and temperature fields make it necessary to solve both fields simultaneously;

  • require the use of coupled thermal-electrical elements, although pure heat transfer elements can also be used in the model;

  • can include a specification of the fraction of electrical energy that will be released as heat;

  • can include thermal interactions such as gap radiation, gap conductance, and heat generation between surfaces (see Thermal contact properties);

  • can include cavity radiation effects (see Cavity Radiation in Abaqus/Standard);

  • can include electrical interactions such as electrical current flowing across surfaces (see Electrical contact properties);

  • allow for transient or steady-state thermal solutions and for steady-state electrical solutions; and

  • can be linear or nonlinear.
