 will be checked before the model is run. If either the runtime parameter or the geometry check indicate non-flat walls,
 the model will terminate. To add FlatWallBounded specific output to the vtk output, WriteFlatWallBoundedFields can be set as True.
 - __1d3d coupling__: The kernel coupling manager has been replaced with the one from Koch et al (2020) JCP https://doi.org/10.1016/j.jcp.2020.109370
+- __1d3d coupling__: The average and surface coupling managers has been updated with a slightly more accurate version to compute the stencils and the average operator.
+The results might differ a bit when using coarse grids. However, both version are expected to converge to the same result with grid refinement.
