While it is designed to be used as a support module to support pyansys, it can be used individually to send text commands to an APDL instance, but with none of the syntax checking or error handling pyansys uses. In short, if you find yourself here, install pyansys _ unless you really want a quick and dirty solution to driving ANSYS APDL from Python. This module relies on documentation provided by ANSYS APDL and uses compiled libraries using both source file from omniORB . See the shell files on the GitHub repository for Linux build instructions. Building for Windows was a nightmare. Installation Pre-compiled binary files are available for Python 2.7, 3.5, and 3.6 for Linux and Windows. Open an issue _ if you need another version. Python 3.7 is unavailable as the source isn't compiling. Wait until 4.2.3 or greater is released. Contact the maintainer at omniORB_. Installation is simply: .. code:: pip install ansys_corba Usage Once again, you really should be using pyansys. It handles figuring out where the mapdl_broadcasts.txt file is and when to open a connection with the server. If you'd rather live on the wild side, here's how you'd open ANSYS, connect to a CORBA server, and send over a few commands: .. code:: python import sys import time import os from ansys_corba import CORBA import subprocess # edit this to match your ansys exe ansys_loc = 'C:\\Program Files\\ANSYS Inc\\v170\\ansys\\bin\winx64\\ANSYS170.exe' # ansys apdl logging here: logfile = 'mapdl_broadcasts.txt' if os.path.isfile(logfile): os.remove(logfile) # make temporary input file to stop ansys from prompting the user with open('tmp.inp', 'w') as f: f.write('FINISH') # start ANSYS command = '"%s" -aas -i tmp.inp -o out.txt -b' % ansys_loc subprocess.Popen(command, stdout=subprocess.PIPE) # monitor log file and wait for connection print('Starting ANSYS...') while True: try: if os.path.isfile(logfile): with open(logfile, 'r') as f: text = f.read() if 'visited:collaborativecosolverunitior' in text: print('ANSYS started') break time.sleep(0.1) except KeyboardInterrupt: sys.exit() with open('./aaS_MapdlId.txt') as f: key = f.read() # create server orb = CORBA.ORB_init() mapdl = orb.string_to_object(key) # run simple commands to demonstrate this works mapdl.executeCommand('/prep7') out = mapdl.executeCommandToString('cylind, 2, , , 2, 0, 90') print(out.replace('\\n', '\n')) mapdl.executeCommand('FINISH') mapdl.terminate() # could use exit, but it returns an error There's several things that could break here, for example, your path to ANSYS, or finding the mapdl_broadcasts.txt file. If this python script isn't running in the same directory as ANSYS, it will hang until you kill the process or exit it with a keyboard interrupt. Further Documentation Once you've opened a connection to ANSYS, there's really only three commands that you need to use. This documentation was shamelessly taken from sharcnet _. executeCommand: Issues a command to the connected Mechanical APDL session. Output from the command is not returned. executeCommandToString Issues a command to the connected Mechanical APDL session and returns the output as a string. terminate Terminates the connected Mechanical APDL as a Server session. See the sharcnet_ documentation for more details Notes Installing from source is not possible using PyPi as the shared libraries need to be compiled outside of Python. I've included docker_buildlinux.sh and docker.sh which can be used to build the source code for Linux. Building for Windows is more complicated and requires following the readme within the omniorb source along with some trial and error. License and Acknowledgments This code is licensed under the MIT license. This module, ansys_corba makes no commercial claim over ANSYS whatsoever. This tool extends the functionality of ANSYS by adding a python interface in both file interface as well as interactive scripting without changing the core behavior or license of the original software. The use of the interactive APDL control of ansys_corba requires a legally licensed local copy of ANSYS. Also, this module wouldn't be possible without omniORB_ as most of the source code is directly take from omniORBpy with only minor modifications to the file structure and the addition of documentation specific to ANSYS.
