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.

Profile Duration Is Too Short

Condition

The Impulse profile will not behave as expected.

Cause

The duration is shorter than the solver output interval.

Remedy

Increase the Duration in the Property Editor.
Increase the Output Rate in the Run Motion Analysis settings.
