Postprocess an assembly

This example shows how to postprocess an assembly with multiple composite parts. The assembly consists of a shell and solid composite model. The Composite Model class is used to access the data of the different parts.

Set up analysis

Setting up the analysis consists of loading Ansys libraries, connecting to the DPF server, and retrieving the example files.

Load Ansys libraries.

from ansys.dpf.composites.composite_model import CompositeModel
from ansys.dpf.composites.constants import FailureOutput
from ansys.dpf.composites.example_helper import get_continuous_fiber_example_files
from ansys.dpf.composites.failure_criteria import CombinedFailureCriterion, MaxStressCriterion
from ansys.dpf.composites.server_helpers import connect_to_or_start_server

Start a DPF server and copy the example files into the current working directory.

server = connect_to_or_start_server()
composite_files_on_server = get_continuous_fiber_example_files(server, "assembly")

Configure combined failure criterion

Configure the combined failure crition.

combined_fc = CombinedFailureCriterion(
    name="failure of all materials",
    failure_criteria=[MaxStressCriterion()],
)

Set up model

Set up the composite model.

composite_model = CompositeModel(composite_files_on_server, server)

Plot IRF

Plot the maximum IRF per element.

output_all_elements = composite_model.evaluate_failure_criteria(combined_criterion=combined_fc)
irf_field = output_all_elements.get_field({"failure_label": FailureOutput.FAILURE_VALUE})
irf_field.plot()

Get element information

In the assembly, two composite definitions exist: one with a “shell” label and one with a “solid” label. To query the lay-up properties, you must query the properties with the correct composite definition label. This code gets element information for all layered elements.

element_infos = []
for composite_label in composite_model.composite_definition_labels:
    for element_id in composite_model.get_all_layered_element_ids_for_composite_definition_label(
        composite_label
    ):
        element_infos.append(composite_model.get_element_info(element_id, composite_label))
