Basics of IcoDyMFoam
- Transient solver- Incompressible-Laminar flow- Newtonian fluids- Moving mesh
Mesh manipulation approaches
- Fixed mesh topology; i.e. spacing between the nodes changes (Automatic approach in IcoDyMFoam)
- Variable mesh topology; with help of:- boundary attachment or detachment- Layer addition or removal-Sliding interfaces
Mesh manipulation models
- dynamicFvMesh library models- staticFvMesh (no change in mesh)- dynamicMotionSolverFvMesh (solving for the cell motion equations)- dynamicInkJetFvMesh (harmonic mesh motion)
- topoChangerFvMesh library models- linearValveFvMesh (sliding interface)- linearValveLayersFvMesh (sliding interface with layer addition and removal)- mixerFvMesh (sliding interface in cylindrical coordinates)- movingConeTopoFvMesh (layer addition and removal)
Point motion solvers
- displacementLaplacian- solving for the laplacian of the diffusivity and cell displacement
- velocityLaplacian- solving for the laplacian of the diffusivity and cell velocity
- SBRStress- a displacement solver, taking care of Solid Body Rotation
Diffusivity models
- quality-based methods- uniform- directional- motion directional- inverseDistance
- distance-based methods- linear- quadratic- exponential
A few examples
