Model (hwx.inspire.core)¶

The active Inspire model. Model is a subclass of Assembly class.

It can be retrieved from and saved to a file. Is contains all the parts, joints, fasteners, load cases, and any other information required for its analysis.

Attribute Details¶

active : Bool¶

Returns or sets the object activeness.

Setting this on or off sets all children. Setting to True sets all the parents active too.

autoCalculateCG : Bool¶

Determines whether the center of gravity is auto calculated.

autoCalculateMass : Bool¶

Determines whether the mass value is automatically calculated based upon volume and material density.

autoCalculateMeshSize : Bool¶

Indicates whether the minimum and average element sizes used for the solution are automatically calculated.

Set to False to enter these values manually.

Decreasing the minimum element size will increase the detail of your results in areas that use a number of small elements. The average element size controls the overall detail of your results.

autoCalculateMoment : Bool¶

Determines whether the mass moment of inertia is automatically calculated.

autoCalculateThickness : Bool¶

Determines whether the minimum and maximum thickness values are automatically calculated.

All parts are taken into account during the calculation.

cg : Location (units=”length”)¶

Returns the object’s global center of gravity as a point.

color : Color¶

Determines the color assigned to the object when it is displayed in the modeling window.

The default color for parts is gray, but a different color can be assigned.

contactSearchDistance : Double (units=”length”)¶

The global contact search distance for model.

detectCollisions : Bool¶

Determines whether to detect collision.

It prevents parts in the model from overlapping and has been enabled by default.

gravityDirection : Direction¶

Returns or sets unitless gravity direction. May not be normalized.

gravityMagnitude : Double (units=”acceleration”)¶

Returns or sets gravity acceleration scalar.

ground : Bool¶

Returns or sets the object to be ground or immovable.

ip : Inertia (units=”massMI”)¶

Specifies the inertial properties of this object.

Resistance to change in motion (ixx, iyy, izz, ixy, izy, ixz).

limitNumberOfElements : Bool¶

If True, limits the mesh size by number of elements.

mass : Double (units=”m”)¶

The mass of the object.

material : Attribute¶

The material of the object.

Every part in the model has a material assigned to it. The default material is steel, but a different material can be assigned.

maxMeshSize : Double (units=”length”)¶

Returns or sets the maximum mesh size of the part.

maxThickness : Double (units=”length”)¶

The maximum thickness value.

minMeshSize : Double (units=”length”)¶

Returns or sets the minimum mesh size of the part.

minThickness : Double (units=”length”)¶

The minimum thickness value.

modifiable : Bool¶

Determines whether the selected object can be edited.

morphable : Bool¶

Determines whether the selected object shape can be changed.

movable : Bool¶

Determines whether the selected object can be translated in the modeling window or has been locked in place.

name : Attribute¶

Returns or sets the name of the object.

It can be any text string, including spaces, although it’s best to avoid using the following characters: ” ‘ * ? and $.

While these characters are allowed, they could create difficulties when you export the model to other applications.

numberOfElements : Int¶

Specifies the number of elements in the mesh.

position : Attribute¶

Specifies the global transform as a Matrix44.

transparency : Double¶

Specifies the transparency of the object.

Allows you to change the transparency, according to a percentage. By default, objects are 0% transparent(opaque).

visible : Bool¶

Determines whether the object is visible in the modeling window.

Setting this on or off sets all children. Setting to True sets all the parents visible too.

volume : Double (units=”volume”)¶

The volume of the object in the assembly.

Method Details¶

getSkinMesh(self, parts, local=False)¶

Returns a dictionary of parts to the skin mesh (nodes and faces).

param parts:	Specify the parts to skin mesh.
