Motion
Inspire Motion provides Multibody Simulation (MBS) capabilities to analyze the motion, dynamics, and interactions of interconnected rigid or flexible bodies within a system.
Motion Designer
The Designer profile adopts a user-centric approach, prioritizing accessibility and ease of use over complexity. While its feature set is less extensive than that of the Analyst profile, it compensates by streamlining functionality and abstracting complexities through intuitive user interactions. This simplicity empowers users outside the traditional Multibody Dynamics (MBD) community to achieve their objectives efficiently, requiring minimal familiarity with MBD.
Motion Forces
Apply motors, actuators, springs, and gravity to define the elements for a motion analysis.
Profiles and Controllers
Motors and actuators have additional options on the microdialog that allow you to change how the shaft moves as time elapses (or another independent variable changes) and control feedback.

- Motion Designer
  The Designer profile adopts a user-centric approach, prioritizing accessibility and ease of use over complexity. While its feature set is less extensive than that of the Analyst profile, it compensates by streamlining functionality and abstracting complexities through intuitive user interactions. This simplicity empowers users outside the traditional Multibody Dynamics (MBD) community to achieve their objectives efficiently, requiring minimal familiarity with MBD.
  - Motion Connections
    Define motion connections by grounding parts and creating rigid groups and joints.
  - Motion Forces
    Apply motors, actuators, springs, and gravity to define the elements for a motion analysis.
    - Motors
      Use the Motors tool to apply a motor to a hole, surface, or pin.
    - Actuators
      Use the Actuators tool to apply an actuator to features or connected parts.
    - Gravity
      Use the Gravity tool to apply gravitational acceleration (G) and adjust its direction.
    - Coil Springs
      Use the Add/Edit Coil Springs tool to apply a translational spring-damper force along the line of sight between two parts.
    - Torsion Springs
      Use the Add/Edit Torsion Springs tool to apply a rotational spring-damper force about the pivot axis for two parts.
    - Motion Contacts
      Use the Contacts tool to create motion contacts between parts or sets of parts.
    - Profiles and Controllers
      Motors and actuators have additional options on the microdialog that allow you to change how the shaft moves as time elapses (or another independent variable changes) and control feedback.
      - Profile Functions

      - Profile Editor
        Use the Profile Editor to view and edit profile functions.
      - Controller
        A controller is provided as a way to try and reach a desired (target) value by means of a feedback control loop.
  - Motion Setup
    Complete the motion setup by creating veloctiy initial conditions and flexible bodies.
  - Motion Analysis
    Run a motion analysis, plot the results, and extract the results for use in structural (FE) analysis and optimization.
- Motion Analyst
  The Analyst profile functions as a feature-rich pre-processor, originally inspired by the needs of the automotive industry. Utilizing a hard-point design approach, it provides access to the full suite of MotionSolve features and capabilities. The Analyst profile offers unparalleled flexibility in system modeling and can be highly tailored to specific industry requirements. However, this versatility comes with increased complexity, requiring a higher level of MBD expertise and a specialized mindset for effective use.
Fluids
Prepare and run a computational fluid dynamics simulation.
Design Explorer
Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.

Profile Parameters

Parameters available in the Profile Editor vary based on what profile function is selected.

Span

The time span from when the waveform begins to when it ends. For example, in the figure below, the time span is 1.8.

The Span and dt are related as the profile curve ramps up over time dt and tails off over time dt to prevent discontinuity in the profile.
