An OpenFOAM function object for CHT, FSI, and fluid-fluid coupled simulations using preCICE.

What is this?

This preCICE adapter is a plug-in (function object) for OpenFOAM, which can work with any recent version of OpenFOAM (.com / .org, see supported OpenFOAM versions). It supports fluid-structure interaction (fluid part), conjugate heat transfer (fluid and solid parts), and fluid-fluid simulations, while it is also easily extensible.

What can it do?

This adapter can read/write the following fields:

  • Temperature (read + write)
  • Heat flux (read + write)
  • Sink temperature (read + write)
  • Heat transfer coefficient (read + write)
  • Force (write)
  • Stress (write)
  • Displacement (read)
  • Displacement delta (read)
  • Pressure (read + write)
  • Pressure gradient (read + write)
  • Velocity (read + write)
  • Velocity gradient (read + write)

All features of preCICE are supported, including implicit coupling and nearest-projection mapping. Even though OpenFOAM is 3D, this adapter can also work in the 2D mode of preCICE, defining only one layer of interface nodes (automatically).

Try

Here you will find how to get the adapter, how to configure a case, how to extend the adapter to cover additional features, as well as a few notes on supported OpenFOAM versions.
