``BldFile`` is the file name of the blade input file. This name should
be in quotations and can contain an absolute path or a relative path.

Pitch Actuator Parameter
~~~~~~~~~~~~~~~~~~~~~~~~

In this release, the pitch actuator implemented in BeamDyn is not
available. The ``UsePitchAct`` should be set to “FALSE” in this
version, whereby the input blade-pitch angle prescribed by the driver
code is used to orient the blade directly. ``PitchJ``, ``PitchK``,
and ``PitchC`` specify the pitch actuator inertial, stiffness, and
damping coefficient, respectively. In future releases, specifying
``UsePitchAct`` :math:`=` TRUE will enable a second-order pitch
actuator, whereby the pitch angular orientation, velocity, and
acceleration are determined by the actuator based on the input
blade-pitch angle prescribed by the driver code.
