  • Versions of solvers and adapters used: OpenFOAM2404,openfoam-adapter-1.3.1

  • preCICE version: precice-3.3.0

  • when I run the case partitioned-backwards-facing-step, this error occured:

Issue resolved. Solution as follows:

  1. As mentioned in precice/tutorials #373, modify all the relevant settings in the configuration file precice-configure.xml:

    <exchange ... substeps="false" />

  2. Add the following to the configuration file precice-configure.xml:

    <acceleration:IQN-ILS>
      ...
      <data mesh="Fluid2-Mesh" name="Pressure" />
      ...
</acceleration:IQN-ILS>
