Initialize the DataStream object

This initializes an object that manages the I/O for all of PVade.

Parameters:

• domain (pvade.geometry.MeshManager.Domain) – A Domain object

• flow (pvade.fluid.FlowManager.Flow) – A Flow object

• params (pvade.Parameters.SimParams) – A SimParams object

save_XDMF_files(fsi_object, domain, tt)
