`invariants`#

class ansys.dpf.core.operators.invariant.invariants.invariants(field=None, config=None, server=None)#

Bases: ansys.dpf.core.dpf_operator.Operator

Computes the element-wise invariants of a tensor field.

Parameters:

field (Field)

Returns:

field_int (Field) – Stress intensity field
field_eqv (Field) – Stress equivalent intensity
field_max_shear (Field) – Max shear stress field

Examples

>>> from ansys.dpf import core as dpf

>>> # Instantiate operator
>>> op = dpf.operators.invariant.invariants()

>>> # Make input connections
>>> my_field = dpf.Field()
>>> op.inputs.field.connect(my_field)

>>> # Instantiate operator and connect inputs in one line
>>> op = dpf.operators.invariant.invariants(
...     field=my_field,
... )

>>> # Get output data
>>> result_field_int = op.outputs.field_int()
>>> result_field_eqv = op.outputs.field_eqv()
>>> result_field_max_shear = op.outputs.field_max_shear()

Overview#

Properties

`inputs`	Enables to connect inputs to the operator
`outputs`	Enables to get outputs of the operator by evaluating it

Static methods
