``SetFieldInterpTimeStep(FieldInterp, TimeStep)``: defines the time step for the interpolation of the field (see :ref:`tui_create_iteration`)
``SetFieldInterpTimeStepRank(FieldInterp, TimeStep, Rank)``: defines the time step and the rank for the interpolation of the field (see :ref:`tui_create_iteration`)
- If error occurs into the python instructions, the program stops.
