Add Potting Regions for PCB Analysis

This example demonstrates how to use the Sherlock gRPC service to: - Import a project. - Add potting regions to a PCB model. - Define potting shapes and properties.

Description

This script connects to the Sherlock gRPC service, imports a project, and creates potting regions.

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

Connect to Sherlock

Connect to the Sherlock service and ensure proper initialization.

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

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}")

Add Potting Region

Define a polygonal shape and add it as a potting region to the PCB.

try:
    # Define the polygonal shape for the potting region
    polygonal_shape = PolygonalShape(points=[(0, 0), (0, 6.35), (9.77, 0)], rotation=87.8)

    # Add the potting region
    sherlock.layer.add_potting_region(
        project="Test",
        potting_regions=[
            {
                "cca_name": "Auto Relay",
                "potting_id": "Test Region",
                "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}")
