The Computed Muscle Control (CMC) Tool is controlled by a window with three tabbed panes (figure below). This window is the same as that used for RRA (see Residual Reduction Algorithm).

Image Modified
  • The Main Settings pane is used to specify parameters related to the input kinematics of the current model, the time range for the analysis, and the output of the results.

  • The Actuators and External Loads pane is used to specify additional actuators, such as residual and reserve actuators.

  • The external loads and integrator settings are specified in the same manner as in Forward Dynamics.

Actuators and External Loads Pane

The Actuators and External Loads pane is used to specify parameters relating to the actuators appended to the model and the external loads applied to the model during CMC. The pane is organized into two main sections entitled Actuators and External Loads.

Image Added
  • The section for Actuators displays editable information that allows you to specify additional force set files that specify forces to supplement the muscles of the model.

  • You may use the Image Added button to edit the list of force set files describing the forces to be appended to or replaced in the model.

Image Added
  •  The information in the External Loads section is optional. 
  • If checked, the section displays information so that you can specify the external loads applied to the model. 
  • Please refer to the section on ExternalLoads specification under the How to Use the Inverse Dynamics Tool for more details.

Command-line Execution

CMC is run using the command cmc -S <setup file> where <setup file> is the name of the setup file, for example,
