PyMechanical integration#
This example demonstrates how to use PyWorkbench and PyMechanical together to upload geometry, run simulations, and visualize results. It covers launching services, running scripts, and handling files between the client and server.
First, import the necessary modules. We import pathlib for handling filesystem paths, os for interacting with the operating system, and pyvista for visualization. The launch_workbench function from ansys.workbench.core is imported to start a Workbench session, and launch_mechanical from ansys.mechanical.core to start a Mechanical session.
[1]:
import os
import pathlib
import pyvista as pv
from ansys.workbench.core import launch_workbench
from ansys.mechanical.core import launch_mechanical
Define several directories that will be used during the session. workdir is set to the parent directory of the current file. assets, scripts, and agdb are subdirectories within the working directory. The launch_workbench function is called to start a Workbench session with specified directories.
[2]:
workdir = pathlib.Path("__file__").parent
assets = workdir / "assets"
scripts = workdir / "scripts"
agdb = workdir / "agdb"
wb = launch_workbench(release="241", server_workdir=str(workdir.absolute()), client_workdir=str(workdir.absolute()))
Upload a geometry file (two_pipes.agdb) from the client to the server using the upload_file method.
[3]:
wb.upload_file(str(agdb / "two_pipes.agdb"))
Uploading two_pipes.agdb: 100%|██████████| 2.27M/2.27M [00:00<00:00, 152MB/s]
Execute a Workbench script (project.wbjn) to create a mechanical system and load the geometry using the run_script_file method. The name of the system created is stored in system_name.
[4]:
system_name = wb.run_script_file(str((assets / "project.wbjn").absolute()))
Start a PyMechanical service for the specified system using the start_mechanical_server method. Create a PyMechanical client connected to this service using launch_mechanical. The project directory is printed to verify the connection.
[5]:
pymech_port = wb.start_mechanical_server(system_name=system_name)
mechanical = launch_mechanical(start_instance=False, ip='localhost', port=pymech_port)
print(mechanical.project_directory)
C:\Users\ansys\AppData\Local\Temp\WB_ansys_6240_2\wbnew_files\
Read and execute the script solve.py via the PyMechanical client using run_python_script. This script typically contains commands to mesh and solve the model. The output of the script is printed.
[6]:
with open(scripts / "solve.py") as sf:
mech_script = sf.read()
print(mechanical.run_python_script(mech_script))
{"total_deformation": "1.9647094770595032E-06 [mm]"}
Fetch output files (*solve.out and *deformation.png) from the solver directory to the client’s working directory using the download method.
[7]:
mechanical.download("*solve.out", target_dir=str(workdir.absolute()))
mechanical.download("*deformation.png", target_dir=str(workdir.absolute()))

The Distributed Sparse Matrix Solver is currently running in the
in-core memory mode. This memory mode uses the most amount of memory
in order to avoid using the hard drive as much as possible, which most
often results in the fastest solution time. This mode is recommended
if enough physical memory is present to accommodate all of the solver
data.

Reading results into the database (SET command) will update the current
displacement and force boundary conditions in the database with the
values from the results file for that load set. Note that any
subsequent solutions will use these values unless action is taken to
either SAVE the current values or not overwrite them (/EXIT,NOSAVE).

Plot the deformation result (deformation.png) using pyvista. A Plotter object is created, and the image is added as a background. The plot is then displayed.
[9]:
pl = pv.Plotter()
pl.add_background_image(os.path.join(str(workdir.absolute()), "deformation.png"))
pl.show()
Finally, the exit method is called on both the PyMechanical and Workbench clients to gracefully shut down the services, ensuring that all resources are properly released.
