Hi,
I would like to inquire if there is a specific meaning or physical concept behind the “Boundary Conditions in Flow Direction” in FlowDict module.
I noticed that the “Boundary Conditions in Flow Direction” can be set to "Periodic" in FlowDict. However, for the simulation model, the voxel size in the flow direction (e.g., the Z-direction) should be constrained and should not be periodically repeated. Otherwise, the thickness of the simulation model may change.
I am wondering if this setting affects the thickness of the model.

Best regards,
Danny
