Coupled Physics
The ANSYS Multiphysics solution provides two powerful methods to couple multiple physics together — Direct and Iterative.
► Direct
• Solves coupled physics equations directly
• Solves each physics simultaneously
► Iterative
• Physics are coupled by passing loads across physics field interfaces
• Solves each physics simultaneously or sequentially
• At least two iterations, one for each physics, in sequence are needed to achieve a coupled response
Providing both coupling methods allows the ANSYS Multiphysics solution to address an
extremely broad range of analysis applications:
Analysis Classes
Low-Frequency Electric
► Quasistatic electric
► Time-harmonic analysis for linear materials
► Time-transient analysis for linear
