How to Use the Software: A Basic Workflow

This guide outlines a standard workflow for conducting a biomechanical analysis.

• Step 1: Load or Build a Model. Begin by loading a pre-built model from the extensive model repository, or use the AnyScript modeling language to construct a custom model from scratch.

• Step 2: Input Movement Data. Drive your digital human model by importing motion capture data (e.g., C3D file format) and external force data (e.g., ground reaction forces from a force plate).

• Step 3: Parameterize the Model. Scale the generic model to match the specific anthropometry of your subject by inputting height, weight, and segment lengths.

• Step 4: Run the Analysis. Execute the inverse dynamics simulation. The software’s solver will calculate muscle activations, joint reaction forces, and moments for every frame of the movement.

• Step 5: Visualize and Export Results. Analyze the results through 2D graphs and 3D animations. Key data, such as peak joint forces or muscle activity over time, can be exported for further analysis in other software or for inclusion in reports.
