Jérôme Duriez proposed the following answer:
Hello,

FlowEngine is for saturated cases. For unsaturated i.e. partially
saturated cases, you should give a look to

- the Capillary model: see [1] and related classes, and the wiki [2]. This is for pendular regime only (see the wiki)
- or the more general UnsaturatedEngine (probably not included by default in any YADE version), see [3]
