    """Specifies a calculation frequency for a field in an ANSYS Multi-field
    APDL Command: MFCALC
    solver analysis.
    Parameters
    ----------
    fnumb
        Field number set by the MFELEM command.
    freq
        Perform calculation every Nth ANSYS Multi-field solver time step.
        Defaults to 1 for every time step.
    Notes
    -----
    This command only applies to a harmonic analysis of the specified
    field. It is useful when a field contributes negligible field
    interaction within a single ANSYS Multi-field solver time step.
    This command is also valid in PREP7.
    See Multi-field Commands in the Coupled-Field Analysis Guide for a list
    of all ANSYS Multi-field solver commands and their availability for MFS
    and MFX analyses.
    Distributed ANSYS Restriction: This command is not supported in
    Distributed ANSYS.
