Remote & Embedding Example#
This code, which uses the same example, first demonstrates how to use a remote session and then demonstrates how to use an embedding instance.
Remote Session#
Download required files#
Download the required files. Print the file paths for the geometry file and script file.
import os
from ansys.mechanical.core import launch_mechanical
from ansys.mechanical.core.examples import download_file
geometry_path = download_file("Valve.pmdb", "pymechanical", "embedding")
print(f"Downloaded the geometry file to: {geometry_path}")
script_file_path = download_file("remote_script.py", "pymechanical", "embedding")
print(f"Downloaded the script file to: {script_file_path}")
Downloaded the geometry file to: /github/home/.local/share/ansys_mechanical_core/examples/Valve.pmdb
Downloaded the script file to: /github/home/.local/share/ansys_mechanical_core/examples/remote_script.py
Launch Mechanical#
Launch a new Mechanical session in batch, setting cleanup_on_exit to
False. To close this Mechanical session when finished, this example
must call the mechanical.exit() method.
import os
from ansys.mechanical.core import launch_mechanical
# Launch mechanical
mechanical = launch_mechanical(batch=True, loglevel="DEBUG")
print(mechanical)

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
