Applications: Overset Course

This course covers Theoretical and Applied concepts using overset (chimera) meshing in OpenFOAM. The course organisers are application experts in all engineering sectors, especially transportation: Automotive, Aerospace, Marine, Rail.

The training provides examples of process and best practice, which are useful to existing OpenFOAM users wishing to broaden their application knowledge of OpenFOAM towards using overset meshing as an alternative to mesh morphing or sliding interfaces.

All features demonstrated in this course are part of the Official release of OpenFOAM.

Topics Covered

  • Meshing for overset
    • basics of background and foreground mesh generation, and assembly
    • interpolation controls, solver settings
  • Basic tutorials
  • heat conduction
    • static aerofoil at several angle of attacks
    • transient cylinder shedding
    • counter-rotating blades
    • 6DoF floating body
  • Limitations, e.g. object collisions
  • Application examples
    • Overtaking vehicles
    • Passing high speed trains
    • Manoeuvring ship including hull, propeller, and rudder interaction
    • Propeller fan
  • Post-processing
  • Running in parallel


  • Applied deflections in interaction pressure zones (FSI, 6DoF)
  • Tips, Tricks and Best practises
  • OpenSource community interactions
