Geometry Modeling
Manage CAD, FE, and 2D parametric sketch geometry.
Meshing
Generate surface/volume mesh by defining mesh controls, or interactively create and edit 2D surface mesh.
Setup
Prepare your model and run the simulation.
Post-Processing
Post-process the simulation results by creating visualizations and measurements.
Automation
Automate simulation processes with templates and utility scripts.
Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Solver Help

Supported Entities

Entities supported by the Inspire reader.

Models
Assemblies
Parts
Solids
Sheets
Curves
Points
Axis Systems
Facets/Triangles
FE Models
Alternatives
- Active alternatives are imported by default.
- All alternatives are imported when hidden (blanked/no show) entities are imported.

The following properties associated to entities are supported:

Visibility
Color
Transparency
Active status
- Active geometry is imported by default.
- All geometry is imported when hidden (blanked/no show) entities are imported.

Import Options

The Inspire reader uses the inspire_reader.ini file.

`@BodyIdAsMetadata`
Value	Description
`on`	Assign body identifier as metadata. `BODY_ID`
`off`	Do not assign body identifier as metadata (default).

`@CleanupTol`
Value	Description
`double`	A negative value (default) indicates to use the auto cleanup tolerance. A value greater than the calculated auto cleanup tolerance indicates to use that specific tolerance. Refer to the CAD Import Options.

`@ColorsAsMetadata`
Value	Description
`integer`	Read color attributes of geometric entities as metadata with integer values. `COLOR_RGB`
`on`	Read color attributes of geometric entities as metadata. `COLOR_RGB`
`off`	Do not read color attributes (default).

`@CreationType`
Value	Description
`Parts`	Generate a full part-based hierarchy.
`BOMOnly`	Generate an empty part-based hierarchy.
`TreeOfComponents`	Generate an assemblies/components based hierarchy.
`PackIntoSinglePart`	Consolidate hierarchy into a single part.

`@DensityAsMetadata`
Value	Description
`on`	Read density value as metadata (default). `DENSITY`
`off`	Do not read density value.

`@DoNotMergeEdges`
Value	Description
`on`	Preserve the original geometry edges, instead of merging them together during the import cleanup phase.
`off`	Merge edges together during the import cleanup phase (default).

`@ExtractManifoldFromGeneralBody`
Value	Description
`on`	Extract the manifold body from a Parasolid general body that is non-manifold and/or of mixed topological dimensionality (default).
`off`	Extract Parasolid general bodies as defined.

`@ImportBlanked`
Value	Description
`on`	Import entities that are hidden, blanked, or no show.
`off`	Do not import entities that are hidden, blanked, or no show (default).

`@ImportFEModels`
Value	Description
`on`	Import FE mdoels (default).
`off`	Do not import FE models.

`@ImportForVisualizationOnly`
Value	Description
`on`	Import the model for visualization purposes only. This skips many of the import steps (cleanup, stitching, solid creation, and so on) to provide a faster import. The resulting model may not be suitable for other uses.
`off`	Import the model in the normal fashion (default).

`@ImportFreeCurves`
Value	Description
`on`	Import free curves (wireframe entities) into the model (default).
`off`	Do not import free curves.

`@ImportFreePoints`
Value	Description
`on`	Import free points into the model (default).
`off`	Do not import free points.

`@LegacyHierarchyAsMetadata`
Value	Description

`off`	Do not generate metadata with the original CAD hierarchy within the part (default).

`@MetadataPrefix`
Value	Description
`string`	The string is prefixed to all metadata names. No prefix is used by default. See CAD Metadata Naming for more details.
