Optimization#

Optimization commands are used to perform topology, shape, or sizing optimization of your model given a set of objectives and a set of restrictions.

Create optimization tasks#

class OptimizationTaskModel(name, description='', stefanBoltzmann=None, absoluteZero=None, waveFormulation=abaqusConstants.NOT_SET, modelType=abaqusConstants.STANDARD_EXPLICIT, universalGas=None, copyConstraints=ON, copyConnectors=ON, copyInteractions=ON)[source]
