Export FEA Model

This example demonstrates how to connect to the Sherlock gRPC service, import a project, and export a Finite Element Analysis (FEA) model.

Description Sherlock’s gRPC API enables automation of various workflows, including exporting FEA models. This script demonstrates how to: - Connect to the Sherlock service. - Import a tutorial project. - Export an FEA model with specific parameters.

import os

from examples.examples_globals import get_sherlock_tutorial_path, get_temp_dir

from ansys.sherlock.core import launcher
from ansys.sherlock.core.errors import (
    SherlockExportFEAModelError,
    SherlockImportProjectZipArchiveError,
)
from ansys.sherlock.core.types.common_types import Measurement

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 provided with the Sherlock installation.

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

Export FEA Model

Export the FEA model with customized parameters.

try:
    fea_export_path = os.path.join(get_temp_dir(), "export.wbjn")
    sherlock.model.export_FEA_model(
        project="Test",
        cca_name="Main Board",
        export_file=fea_export_path,
        analysis="NaturalFreq",
        drill_hole_parameters=[
            {
                "drill_hole_modeling": "ENABLED",
                "min_hole_diameter": Measurement(value=1.0, unit="mm"),
                "max_edge_length": Measurement(value=1.0, unit="mm"),
            }
        ],
        detect_lead_modeling="ENABLED",
        lead_model_parameters=[
            {
                "lead_modeling": "ENABLED",
                "lead_element_order": "First Order (Linear)",
                "max_mesh_size": Measurement(value=1.0, unit="mm"),
                "vertical_mesh_size": Measurement(value=0.5, unit="mm"),
                "thicknessCount": 3,
                "aspectRatio": 2,
            }
        ],
        display_model=False,
        clear_FEA_database=True,
        use_FEA_model_id=True,
        coordinate_units="mm",
    )
    print(f"FEA model exported successfully to: {fea_export_path}")
except SherlockExportFEAModelError as e:
    print(f"Error exporting FEA model: {e}")
