Run Random Vibration Analysis

This example demonstrates how to connect to the Sherlock gRPC service, import a project, add strain maps, and run random vibration analysis.

Description

Sherlock allows you to perform random vibration analysis using strain maps. This script performs the following steps: - Connect to the Sherlock service. - Import a project. - Add a strain map file to the project. - Configure the properties for random vibration analysis. - Execute random vibration analysis based on the configured properties.

import os

from ansys.api.sherlock.v0 import SherlockAnalysisService_pb2
from examples.examples_globals import get_sherlock_tutorial_path

from ansys.sherlock.core import launcher
from ansys.sherlock.core.errors import (
    SherlockAddStrainMapsError,
    SherlockImportProjectZipArchiveError,
    SherlockRunStrainMapAnalysisError,
    SherlockUpdateRandomVibePropsError,
)
from ansys.sherlock.core.types.project_types import StrainMapsFileType

Connect to Sherlock

Connect to the Sherlock service and ensure proper initialization.

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

    raise SherlockConnectionError(message="Error starting gRPC service")
ansys.sherlock.core.errors.SherlockConnectionError: gRPC connection error: Error starting gRPC service

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(), "Tutorial Project.zip"),
    )
    print("Tutorial project imported successfully.")
except SherlockImportProjectZipArchiveError as e:
    print("Error importing project zip archive.")

Add Strain Map

Add a strain map to the project.

try:
    strain_map_path = os.path.join(get_sherlock_tutorial_path(), "StrainMaps", "StrainMap.csv")
    sherlock.project.add_strain_maps(
        project="Test",
        strain_maps=[
            (
                strain_map_path,
                "This is the strain map file for the project",
                StrainMapsFileType.CSV,
                0,
                "SolidID",
                "PCB Strain",
                "µε",
                ["Main Board"],
            )
        ],
    )
    print("Strain maps added successfully.")
except SherlockAddStrainMapsError as e:
    print("Error adding strain maps.")

Update Random Vibration Properties

Configure properties for random vibration analysis using strain maps.

try:
    sherlock.analysis.update_random_vibe_props(
        project="Test",
        cca_name="Main Board",
        model_source=SherlockAnalysisService_pb2.ModelSource.STRAIN_MAP,
        random_vibe_damping="0.01",
        part_validation_enabled=False,
        require_material_assignment_enabled=True,
        analysis_temp=20,
        analysis_temp_units="C",
        force_model_rebuild="AUTO",
        natural_freq_min=10,
        natural_freq_min_units="Hz",
        natural_freq_max=1000,
        natural_freq_max_units="KHz",
        reuse_modal_analysis=True,
        strain_map_natural_freqs="100, 200, 300",
    )
    print("Random vibration properties updated successfully.")
except SherlockUpdateRandomVibePropsError as e:
    print("Error updating random vibration properties.")

Run Random Vibration Analysis

Run the random vibration analysis, including specified parameters.

try:
    analysis_request = SherlockAnalysisService_pb2.RunStrainMapAnalysisRequest
    strain_map_analysis_type = (
        SherlockAnalysisService_pb2.RunStrainMapAnalysisRequest.StrainMapAnalysis.AnalysisType
    )
    random_vibe = strain_map_analysis_type.RandomVibe
    sherlock.analysis.run_strain_map_analysis(
        project="Test",
        cca_name="Main Board",
        strain_map_analyses=[
            [
                random_vibe,
                [
                    ["On The Road", "1 - Vibration", "TOP", "StrainMap - Top"],
                    ["On The Road", "1 - Vibration", "BOTTOM", "StrainMap - Bottom"],
                ],
            ]
        ],
    )
    print("Random vibration analysis completed successfully.")
except SherlockRunStrainMapAnalysisError as e:
    print("Error running random vibration analysis.")
