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)
