Perform compliance analysis on materials data stored in Granta MI.

Project description

Project Overview

This project is part of the larger PyAnsys effort to facilitate the use of Ansys technologies directly from within Python.

The Granta MI Restricted Substances solution includes a REST API for evaluating compliance of products, assemblies, specifications and materials against legislations. This package abstracts automatically- generated code into an easy-to-use client library.


Install ansys-grantami-bomanalytics with:

pip install ansys-grantami-bomanalytics

Alternatively, clone and install with:

git clone
cd grantami-bomanalytics
pip install .


See Granta MI BoM Analytics Documentation for more details.


Here’s a brief example of how the package works:

# Connect and query the Granta service.

>>> from pprint import pprint
>>> from ansys.grantami.bomanalytics import Connection, queries
>>> cxn = Connection("http://my_grantami_server/mi_servicelayer").with_autologon().connect()
>>> query = (
...     queries.MaterialImpactedSubstancesQuery()
...     .with_material_ids(['plastic-abs-pvc-flame'])
...     .with_legislations(['REACH - The Candidate List'])
... )

# Print out the result from the query.

>>> result =
>>> pprint(result.impacted_substances)
[<ImpactedSubstance: {"cas_number": 10108-64-2, "percent_amount": 1.9}>,
 <ImpactedSubstance: {"cas_number": 107-06-2, "percent_amount": None}>,
 <ImpactedSubstance: {"cas_number": 115-96-8, "percent_amount": 15.0}>,
