MpCCI CouplingEnvironment
Driven Cavity (MpCCI V4.7)
Video Player is loading.
This is a modal window.
The media could not be loaded, either because the server or network failed or because the format is not supported.
A flow-through cavity with movable top and flexible bottom. The low structural stiffness leads to a strong added mass effect. Only iterative coupling leads to a stable simulation. The Quasi-Newton relaxation is used in order to accelerate the convergence in each time step.
- Coupling type: Fluid-structure interaction (FSI)
- Analysis type: Implicit transient
- Special topics: Quasi-Newton relaxation, adaptive time step size
- Codes:
- Fluid mechanics: FLUENT, OpenFOAM
- Solid mechanics: Abaqus, MSC NASTRAN
- Quantities: NPosition, WallForce
Thermal Coupling of an Exhaust Manifold (MpCCI V4.6)
Video Player is loading.
This is a modal window.
The media could not be loaded, either because the server or network failed or because the format is not supported.
The simulation uses an exhaust manifold to couple a solid heat transfer model with a fluid heat transfer model in a steady state analysis. Prior to a coupled simulation an uncoupled flow simulation with simplified boundary conditions is carried out.
- Coupling type: Thermal surface coupling
- Analysis type: Steady state with pre-computed flow field
- Special topics: Subcycling of fluid solver, incompressible fluid, 3D-model
- Codes:
- Solid heat transfer: Abaqus, ANSYS, MSC Marc
- Fluid heat transfer: FLUENT, OpenFOAM, STAR-CCM+
- Quantities: FilmTemp, WallHTCoeff, WallTemp
