Tutorials
Start using Inspire with our interactive tutorials.
Variables
Create and assign variables to parametrize a model. This allows you to quickly iterate and compare design concepts by tweaking the values of the variables.
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
Set up and run a motion analysis, plot the results, and export the results.
- 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.
- Motion Setup
  Complete the motion setup by creating veloctiy initial conditions and flexible bodies.
  - Variables in Inspire Motion
    Designate variables as the values of certain Motion entities such as spring stiffness, initial condition rates, actuator inputs, and motor inputs.
  - Design Exploration in Motion
    Use Inspire Design Exploration to perform Inspire Motion DOE and optimization studies.
  - Translational ICs
    Use the Translational IC Sets tool to define translational velocity for one or more parts.
  - Rotational ICs
    Use the Rotational IC Sets tool to define rotational velocity for one or more parts.
  - Flexible Bodies
    Convert rigid bodies or rigid groups to flexible bodies and review flexible body modes before running a motion analysis.
- Motion Analysis

Variables in Inspire Motion

Designate variables as the values of certain Motion entities such as spring stiffness, initial condition rates, actuator inputs, and motor inputs.

Benefit

Control the designated variables in a single location, using the Variable Manager.

Example Use Cases

Use a single stiffness and damping rate to control multiple spring-dampers in the model.
Define a user expression for an actuator that is based on a mathematical relationship to another input variable.
