# Abaqus Multiphysics Coupling and Co-simulation
|
|
|
|
## Definition
|
|
|
|
Abaqus multiphysics coupling and co-simulation are workflows for coupling structural, thermal, fluid, electromagnetic, acoustic, logical, and other analysis domains either within Abaqus procedures or at run time with other solvers.
|
|
|
|
## How It Works
|
|
|
|
Sequential coupling uses results from one analysis as predefined fields or loads in a later analysis. Common fields include temperature, normalized concentration, and electric potential. A common workflow is uncoupled heat transfer followed by thermal-stress analysis, where temperature history is read from the output database or results file and interpolated into the stress analysis.
|
|
|
|
Co-simulation performs run-time coupling between Abaqus and another Abaqus analysis or a third-party program. The coupled domains exchange data over a common interface in a synchronized way. Examples include fluid-structure interaction, conjugate heat transfer, electromagnetic-thermal coupling, electromagnetic-mechanical coupling, Standard/Explicit structural partitioning, and structural-logical coupling with system-level models.
|
|
|
|
## Why It Matters
|
|
|
|
Coupled physics can be too expensive, too specialized, or too weakly coupled to solve with one monolithic procedure. Sequential coupling and co-simulation let analysts choose the coupling strength and solver boundary deliberately.
