The command is used in the following manner:
splitMesh <root> <caseName> <name_of_internal> <name_A> <name_B>
where <name_of_internal> is the name of the cell set you want to split up, <name_A> and <name_B> are the names of the boundaries being created as the result of the split.
The command is also applied in the process of importing Fluent-Meshes with internal boundaries.
