Add and Update Potting Regions

This example demonstrates how to connect to the Sherlock gRPC service, import a project, add potting regions, update existing potting regions, and properly close the connection.

Description

Sherlock’s gRPC API allows users to automate workflows such as adding and updating potting regions for CCAs. This script demonstrates how to: - Connect to the Sherlock service. - Import a project. - Add a potting region. - Update an existing potting region.

import os

from examples.examples_globals import get_sherlock_tutorial_path

from ansys.sherlock.core import launcher
from ansys.sherlock.core.errors import (
    SherlockAddPottingRegionError,
    SherlockImportProjectZipArchiveError,
)
from ansys.sherlock.core.types.layer_types import (
    PolygonalShape,
    PottingRegion,
    PottingRegionUpdateData,
    UpdatePottingRegionRequest,
)

Connect to Sherlock

Connect to the Sherlock service and ensure proper initialization.

sherlock = launcher.connect(port=9092, timeout=10)

Traceback (most recent call last):

FileNotFoundError: Certificate file not found: certs\ca.crt. Ensure that the certificates are present in the 'certs' folder or set the 'ANSYS_GRPC_CERTIFICATES' environment variable.

Delete Project

Delete the project if it already exists.

try:
    sherlock.project.delete_project("Test")
    print("Project deleted successfully.")
except Exception:
    pass

Import Tutorial Project

Import the tutorial project zip archive from the Sherlock tutorial directory.

try:
    sherlock.project.import_project_zip_archive(
        project="Test",
        category="Demos",
        archive_file=os.path.join(get_sherlock_tutorial_path(), "Auto Relay Project.zip"),
    )
    print("Tutorial project imported successfully.")
except SherlockImportProjectZipArchiveError as e:
    print(f"Error importing project zip archive: {e}")

potting_region_id = "Test Region"

Add Potting Region

Add a new potting region to a CCA.

try:
    polygonal_shape = PolygonalShape(
        points=[
            (0, 0),
            (0, 6.35),
            (9.77, 0),
        ],
        rotation=87.8,
    )
    sherlock.layer.add_potting_region(
        project="Test",
        potting_regions=[
            {
                "cca_name": "Auto Relay",
                "potting_id": potting_region_id,
                "side": "TOP",
                "material": "epoxyencapsulant",
                "potting_units": "in",
                "thickness": 0.1,
                "standoff": 0.2,
                "shape": polygonal_shape,
            },
        ],
    )
    print("Potting region added successfully.")
except SherlockAddPottingRegionError as e:
    print(f"Error adding potting region: {e}")

Update Potting Region

Update an existing potting region.

update_data = PottingRegionUpdateData(
    potting_region_id_to_update=potting_region_id,
    potting_region=PottingRegion(
        cca_name="Main Board",
        potting_id="Updated Test Region",
        potting_side="BOT",
        potting_material="epoxyencapsulant",
        potting_units="mm",
        potting_thickness=0.3,
        potting_standoff=0.1,
        shape=PolygonalShape(
            points=[(0, 1), (5, 1), (5, 5), (1, 5)],
            rotation=45.0,
        ),
    ),
)

try:
    update_request = UpdatePottingRegionRequest(
        project="Test",
        update_potting_regions=[update_data],
    )
    sherlock.layer.update_potting_region(update_request)
    print("Potting region updated successfully.")
except Exception as e:
    print(f"Error updating potting region: {e}")
