Tutorials
Start using Inspire with our interactive tutorials.
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.
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.
Manufacture
Set up and run a basic porosity or thinning analysis.
Print 3D
Prepare and run an additive manufacturing simulation, and export a file for 3D printing.
Rendering
Adjust the materials and environment of objects in the scene to create a photorealistic image.
Inspire Python API
Learn how to access the Inspire Python API including online help, quick start demos, and the Extension Manager.

Invalid Coupler

Condition

Motion analysis won't run because a joint coupler is invalid. This error can be triggered by three different causes.

Cause 1: The listed joints cannot be coupled

Click Fix to automatically change the joint type or click Review to manually change it.

Cause 2: Only one translational and one rotational degree of freedom on a single axis is allowed

Click Review and change the listed entity so that it has freedom on or about only one axis.

Cause 3: The listed entity does not have an implicit joint that can be coupled

Click Review to manually change the entity's settings in the Property Editor to make it suitable for coupling, or delete it.
