Detailed Description

Defines parameters used by the mesh generator.

Parameters can be set to and retrieved from the mesh generator using MeshGenerator.SetParameters() and MeshGenerator.Parameters() methods respectively.

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

Member Enumeration Documentation

GranularityType

enum cadex.ModelAlgo.MeshGeneratorParameters.GranularityType

Defines target accuracy of the mesh to be generated.

Provides predefined values for chordal and angular deflections:

	Fine	Medium	Coarse
chordal deflection	0.004 (0.4%)	0.01 (1%)	0.05 (5%)
angular deflection	20 degrees	45 degrees	60 degrees

The predefined values are applied when invoking MeshGeneratorParameters.SetGranularity().

Chordal and angular deflections can also be set to explicitly specified values using MeshGeneratorParameters.SetChordalDeflection() and MeshGeneratorParameters.SetAngularDeflection() methods.

Constructor & Destructor Documentation

MeshGeneratorParameters() [1/2]

cadex.ModelAlgo.MeshGeneratorParameters.MeshGeneratorParameters ( )

inline

Sets default parameter values according to GranularityType.Fine.

See also

SetGranularity(). Constructor.

MeshGeneratorParameters() [2/2]

cadex.ModelAlgo.MeshGeneratorParameters.MeshGeneratorParameters ( cadex.ModelAlgo.MeshGeneratorParameters.GranularityType theGranularity )

inline

Sets default parameter values according to theGranularity.

See also

SetGranularity(). Constructor.

Member Function Documentation

AngularDeflection()

double cadex.ModelAlgo.MeshGeneratorParameters.AngularDeflection ( )

inline

Returns angular deflection.

See also

SetAngularDeflection().

ChordalDeflection()

double cadex.ModelAlgo.MeshGeneratorParameters.ChordalDeflection ( )

inline

Returns a relative or absolute value of the chordal deflection depending on the value returned by IsRelativeChordalDeflection().

Default value is 0.004 (0.4%) when IsRelativeChordalDeflection() is true.

See also

SetChordalDeflection(). Returns chordal deflection.

Dispose()

override void cadex.ModelAlgo.MeshGeneratorParameters.Dispose ( bool disposing )

inlineprotectedvirtual

Reimplemented from cadex.BaseObject.

Granularity()

cadex.ModelAlgo.MeshGeneratorParameters.GranularityType cadex.ModelAlgo.MeshGeneratorParameters.Granularity ( )

inline

Returns a granularity value.

See also

SetGranularity().

IsRelativeChordalDeflection()

bool cadex.ModelAlgo.MeshGeneratorParameters.IsRelativeChordalDeflection ( )

inline

By default, it is true.

See also

SetIsRelativeChordalDeflection(). Returns whether ChordalDeflection() contains an absolute or relative value.

SetAngularDeflection()

void cadex.ModelAlgo.MeshGeneratorParameters.SetAngularDeflection ( double theValue )

inline

Specifies a maximum deviation (in radians) between tangents at two adjacent mesh nodes when tessellating an edge curve or between normals when tessellating a face surface.

Default value in radians is equal to 20 degrees.

Sets granularity to Custom. Sets angular deflection.

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

SetChordalDeflection()

void cadex.ModelAlgo.MeshGeneratorParameters.SetChordalDeflection ( double theValue )

inline

Specifies either a value relative to the body bounding box (if IsRelativeChordalDeflection() is true) or an absolute value of the maximum deflection of the visualization mesh.

Chordal deflection is basically a deviation of the triangles from the original surfaces or curves. Default value is 0.004 (0.4%) when IsRelativeChordalDeflection() is true.

Note that in some cases the algorithm can produce more coarse triangulation.

Sets granularity to Custom.

See also

ChordalDeflection(). Sets chordal deflection.

Examples

meshing/mesh_generation/Program.cs, and meshing/mesh_generation/main.cxx.

SetGranularity()

void cadex.ModelAlgo.MeshGeneratorParameters.SetGranularity ( cadex.ModelAlgo.MeshGeneratorParameters.GranularityType theGranularity )

inline

If theGranularity is Custom, the method does nothing.

Otherwise sets chordal and angular deflections according to the specified granularity value. Refer to the table in the description of the GranularityType. IsRelativeChordalDeflection() is set to true.

See also

GetGranularity().

SetIsRelativeChordalDeflection()

void cadex.ModelAlgo.MeshGeneratorParameters.SetIsRelativeChordalDeflection ( bool theValue )

inline

Specifies whether ChordalDeflection() contains an absolute (if false) or a relative to the shape bounding box (if true, by default) value of the deflection.

Sets granularity to Custom.

See also

IsRelativeChordalDeflection() Sets whether ChordalDeflection() contains an absolute or relative value.
