OpenFOAM® tutorial : Open-water propeller KP 505 modeling (overset mesh)


overPimpleDyMFoam solver



This tutorial shows how to use mesh meshes with OpenFOAM®. The study case (3D) is a ship propeller (kp505 model : in open-water at constant rotational speed of 100 rad/sec (950 rpm). This kind of numerical model is often used for assessing open-water performances curves of propellers (KT, KQ). The mesh overset technique is used to capture solid body movements and is particularly interesting for large displacements or rotation, where mesh deformation methods fail.

  • The tutorial uses the overPimpleDyMFoam solver (pimple version with the mesh overset technique) introduced since the 1706+ version of OpenFOAM

Calculation time:

  • Around 8 hours on 4 cores – i7-4700MQ CPU @ 2.40GHz.


  • OpenFOAM®: Tested on versions 1812+ // 1906+. Warning, the tutorial does not work with versions (4.0, 5.0, 6.0, 7.0 etc.) from the OpenFOAM® Foundation (

  • The tutorial is designed to run on 4 cores but can be easily modified to be run on the number of core chosen by the user.
  • 8 Gb of RAM.
  • It is recommended that you use the latest version of OpenFOAM® + to improve the performance of the overset module.

  • Paraview (post-processing).
