Multiphysics – Combined Analysis Types

Multiphysics analyses link the effects of multiple analysis types. A result from one analysis is used as a load in a subsequent analysis. Here are a couple of multiphysics scenarios:

• Heat Generation Due to Electrical Current:

  Electrical current in a wire generates heat. Perform the electrostatic analysis first to determine the current in a conductor produced by an applied voltage. Then, use the electrical current results in a subsequent heat transfer analysis to generate heat and determine the resultant temperatures. For more information, check out the following analysis examples:

  1. Heat Generation Due to Electrical Current (Electrostatic Current and Voltage Analysis)
  2. Heat Generation Due to Electrical Current (Steady-State Heat Transfer Analysis)
• Thermal Stress:

  Determine the thermal stress of a tank. Perform a steady-state or transient heat transfer analysis first. Then include the temperature results in a subsequent linear static or nonlinear (MES) stress analysis. For more information, check out the following linear static thermal stress example:

  2. Thermal Stress of a Tank (Linear Static Stress Analysis)
