# 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.
|
|
|
|
[[Abaqus-Analysis-User-s-Guide-Volume-III|Volume III]] adds the material definitions that make many coupled procedures meaningful: conductivity and specific heat for thermal coupling, diffusivity and solubility for mass diffusion, piezoelectric and electromagnetic properties for electromechanical coupling, and permeability/sorption/swelling data for pore-fluid stress coupling.
|
|
|
|
[[Abaqus-Analysis-User-s-Guide-Volume-IV|Volume IV]] adds the element families that carry many coupled fields: thermally coupled solid and shell variants, pore-pressure elements, acoustic elements, fluid continuum elements, fluid pipe and fluid pipe connector elements, and Eulerian elements.
|
|
|
|
[[Abaqus-Analysis-User-s-Guide-Volume-V|Volume V]] adds the boundary and interaction side of coupling: predefined fields carry sequentially coupled results, contact properties can include thermal, electrical, and pore-fluid transfer, and cavity radiation defines radiative thermal interaction among surfaces.
|
|
|
|
## 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.
|
|
|
|
