  1. Introduction to OpenFOAM A tutorial on how to use dynamic mesh solver IcoDyMFoam Performed by: Pirooz Moradnia Spring 2008, Göteborg-Sweden

  2. Table of Contents Basics of IcoDyMFoam Mesh manipulation approaches Mesh manipulation models Point motion solvers Diffusivity models A few examples

  3. Basics of IcoDyMFoam Transient solver Incompressible-Laminar flow Newtonian fluids Moving mesh

  4. 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

  5. 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)

  6. 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

  7. Diffusivity models quality-based methods uniform directional motion directional inverseDistance distance-based methods linear quadratic exponential

  8. A few examples
