original_docstring: Specifies the Naval Research Laboratory (NRL) sum mode combination
  
          APDL Command: NRLSUM
          method.
  
          Parameters
          ----------
          signif
              Combine only those modes whose significance level exceeds the
              SIGNIF threshold. For single point, multipoint, or DDAM response
              (SPOPT,SPRS, MPRS or DDAM), the significance level of a mode is
              defined as the mode coefficient of the mode, divided by the maximum
              mode coefficient of all modes. Any mode whose significance level is
              less than SIGNIF is considered insignificant and is not contributed
              to the mode combinations. The higher the SIGNIF threshold, the
              fewer the number of modes combined. SIGNIF defaults to 0.001. If
              SIGNIF is specified as 0.0, it is taken as 0.0. (This mode
              combination method is not valid for SPOPT,PSD.)
  
          label
              Label identifying the combined mode solution output.
  
              DISP - Displacement solution (default). Displacements, stresses, forces, etc., are
                     available.
  
              VELO - Velocity solution. Velocities, "stress velocities," "force velocities," etc.,
                     are available.
  
              ACEL - Acceleration solution. Accelerations, "stress accelerations," "force
                     accelerations," etc., are available.
  
          labelcsm
              Label identifying the CSM (Closely Spaced Modes) method.
  
              CSM - Use the CSM method.
  
              Blank  - Do not use the CSM method (default).
  
          forcetype
              Label identifying the forces to be combined:
  
              STATIC - Combine the modal static forces (default).
  
              TOTAL - Combine the modal static plus inertial forces.
  
          Notes
          -----
          This command is also valid in PREP7. This mode combination method is
          usually used for SPOPT,DDAM.
  
          This CSM method is only applicable in a DDAM analysis (SPOPT,DDAM). The
          CSM method combines two closely spaced modes into one mode when their
          frequencies are within 10 percent of the common mean frequency and
          their responses are opposite in sign. The contribution of these closely
          spaced modes is then included in the NRL sum as a single effective
          mode. Refer to Closely Spaced Modes (CSM) Method in the Mechanical APDL
          Theory Reference for more information.
