ConcentratedMass (hwx.inspire.core)

ConcentratedMass creates a mass only object either on a part or at a point in space.

Concentrated Masses are useful when you need to account for the mass of a part but you do not want the complexity of the geometry to slow down the run. An example would be when running an optimization using frequency constraints or when analyzing for normal modes. When gravity is applied during optimization or analysis, the mass will impart a load on the structure.

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.

associatedFeatures : Attribute

autoCalcMotionContactResolution : Bool

Returns or sets the motion contact fidelity properties from the part.

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.

connectionRadius : Double (units=”length”)

The search radius for the Concentrated Mass.

designSpace : Bool

Determines whether the part is a design space.

A part must be designated as a design space if we intend to optimize it.

detectCollisions : Bool

Determines whether to detect collision.

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

flexible : Bool

Makes the part flexible, if set to True.

ground : Bool

Returns or sets the object to be ground or immovable.

ignoreFlexibility : Bool

Allows the part to ignore flexibility.

ip : Inertia (units=”massMI”)

Specifies the inertial properties of this object.

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

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.

maxFreq : Double (units=”frequency”)

Upper bound frequency for the eigenvalue analysis of the flexible part.

maxMeshSize : Double (units=”length”)

Returns or sets the maximum mesh size of the part.

maxThickness : Double (units=”length”)

The maximum thickness value.

minGap : Double (units=”length”)

minMeshSize : Double (units=”length”)

Returns or sets the minimum mesh size of the part.

minThickness : Double (units=”length”)

The minimum thickness value.

modeType : Enum

How normal modes are defined.

modifiable : Bool

Determines whether the selected object can be edited.

morphable : Bool

Determines whether the selected object shape can be changed.

motionContactResolution : Enum (verylow, low, medium, high, veryhigh)

The resolution of the motion contact. It can be:

  • “verylow”
  • “low”
  • “medium”
  • “high”
  • “veryhigh”

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.

numModes : Int

Specifies the number of modes of the part.

position : Attribute

Specifies the global transform as a Matrix44.

rigidGroup : Attribute

The rigid group this object belongs to.

sheetThickness : Double (units=”length”)

Thickness of the 2D part used in volume calculation.

strainCalculation : Bool

Determines whether to calculate the strain or not.

stressCalculation : Bool

Determines whether to calculate stress or not.

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.
