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 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.
Motion Connections
Define motion connections by grounding parts and creating rigid groups and joints.
Advanced Joints
Use the Advanced Joints tool to create and edit a set of special constraints called higher pair joints. Typically, these are constraints that involve a curve or surface on at least one of the two parts.

Parametric Modeling
Create parametric sketches, geometry, and PolyNURBS with construction history and variables.
Implicit Modeling
Create implicit models with primitives, lattices, point clouds, fields, offsetting, Booleans, inverting, smoothing, morphing, and filleting.
Structures
Set up your model and run a structural analysis or optimization.
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.

  - Entity Creation
    General workflows to add or edit an entity in Inspire Motion Analyst.
  - Expressions
    Motion Analyst entities support expressions.
  - Pairs and Symmetric Modeling in Inspire Motion
    Inspire Motion supports symmetrical modeling, leveraging geometric or physical symmetry in mechanical systems to simplify both modeling and editing. Symmetrical modeling takes advantage of mirrored or repeated components, allowing systems to be represented with fewer entities and parameters.
  - Attachments
    Attachments offer a means to connect definition-based analyst entities such as systems, analyses, data sets and templates.
  - Motion Create
  - Motion Connections
    Define motion connections by grounding parts and creating rigid groups and joints.
    - Ground
      Use the Ground tool to define which parts are considered to be ground and therefore immovable.
    - Rigid Groups
      Use the Rigid Groups tool to define which parts are considered to be grouped together and treated as one rigid body.
    - Joints
      Use the Joints tool to create and edit joints.
    - Couplers
      A coupler entity defines an algebraic relationship between the degrees of freedom of two or three joints.
    - Gears
    - Advanced Joints
      Use the Advanced Joints tool to create and edit a set of special constraints called higher pair joints. Typically, these are constraints that involve a curve or surface on at least one of the two parts.
    - Constraint Mates
      Use the Constraint Mates tool to connect two parts based on distance, coincidence, or tangency.
    - General Constraints
      Use the General Constraints tool to create a generic expression-based constraint.
  - Motion Forces
    Apply motors, actuators, springs, and gravity to define the elements for a motion analysis.
  - Flexible Bodies
    Convert rigid bodies or rigid groups to flexible bodies and review flexible body modes before running a motion analysis.
  - Motion References
  - Motion Measurements
  - Motion Control
  - Motion Analysis
    Run a motion analysis, plot the results, and extract the results for use in structural (FE) analysis and optimization.
Fluids
Prepare and run a computational fluid dynamics simulation.
Design Explorer

Advanced Joints

Use the Advanced Joints tool to create and edit a set of special constraints called higher pair joints. Typically, these are constraints that involve a curve or surface on at least one of the two parts.

Table 1. Advanced Joint Constraints
Advanced Joint Type	Removes Translational DOF	Removes Rotational DOF	Removes Total Number of DOF
Point to Curve	2	0	2
Curve to Curve	1	2	3
