composite:multiple_failure_criteria_operator

Last update: 31.07.2026

Version: 0.0.0

Description

Uses failure configuration, CMeshedRegion and stress and strain fields to compute failure criteria and extracts the maximum over all criteria.

Inputs

Input Name Expected type(s) Description
Pin 7
Required
mesh abstract_meshed_region The mesh region which is consistent with the strain and stress containers.
Pin 23
Required
materials_container materials_container
Pin 24
Required
section_data_container fields_container Section data fields container. Only needed for some of the failure criteria evaluations.
Pin 25
Required
mesh_properties_container fields_container Mesh property fields container. Only needed if eLayupModelContextPin (218) is true.
Pin 100
Required
configuration string Combined failure criterion configuration (string of json dict
Pin 102
Required
check_meshed_region bool The check is enabled by default but it can be costly if the meshes are huge.
Pin 103
Required
is_acp_composite_model bool Deprecated since 2024 R2. Please use eLayupModelContextPin (pin 218). Set to true for ACP composites models. Default is false.
Pin 104
Required
skip_sandwich_criteria bool Skip the sandwich criteria. This should be true if not all plies are selected in which case sandwich criteria cannot be evaluated in a meaningful way. Default is false.
Pin 218
Required
layup_model_context_type int32 Define the source of section data. Values are: 0=not available, 1=ACP, 2=RST, 3=MIXED (ACP+RST). Default is not available.
Pin 400
Required
strains_container fields_container CFieldsContainer with strains
Pin 401
Required
stresses_container fields_container CFieldsContainer with stresses
