Coupled Eulerian-Lagrangian

Abaqus Unified FEA

The Coupled Eulerian-Lagrangian (CEL) approach in Abaqus which provides engineers and scientists with the ability to simulate a class of problems where the interaction between structures and fluids is important. This capability does not rely on the coupling of multiple software products, but instead solves the fluid-structure interaction (FSI) simultaneously within Abaqus.


  • Gas-flow inflated automotive airbags
  • Tire hydroplaning
  • Wave loading on offshore structures
  • Cosmetic product dispensing
  • Fuel tank sloshing
  • High-velocity impact and penetration
  • Soil-structure interaction, such as excavation and gouging
