ConcentratedMass (hwx.inspire)

class ConcentratedMass(parent=None, associatedFeatures=None, **kwds)

Bases: Part

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.

Example

from hwx import inspire

model = inspire.newModel()
part = inspire.ConcentratedMass(mass=0.5, location=(1, 1, 1))

print("Part mass is: " + str(part.mass))
print("Part location is: " + str(part.location))
print("Part center of gravity is: " + str(part.cg))
print("Part has " + str(len(part.features)) + " features")
print("Feature is: " + str(part.features[0]))

part.mass = 1
part.location = (2, 2, 2)
print("Part mass is: " + str(part.mass))
print("Part location is: " + str(part.location))
print("Part center of gravity is: " + str(part.cg))
