pansys

Work interactively with ANSYS mechanical APDL and python.

The pansys module helps you interact with ansys through python. Starting a panys session is as easy as setting a variable.

    from pansys import Ansys
    ans = Ansys()

Now you're ready to send commands to your newly created ansys session.

    ans.send("/prep7")
    ans.send("""n,,1
        n,,2""")

As you must have guessed, ans.send command will let you send commands from python to ansys in string format.

You can get data out of Ansys as well.

    nmax = ans.get("node","","num","max")
    ncount = ans.get("node","","count","")

Using get_list() function, you can get any ansys list item as well.

    nodes = ans.get_list("nlist")

You can also start an ansys session in a remote machine. You will have to set up your ssh keys for this to work.

    ans = Ansys(host="remotesystem")

Look into the documentation to get to know the API better.

Installation

As of now, pansys is supported only on Linux systems. You will also need ANSYS installation on your computer (or on the remote system, if you are using the host option when you're starting pansys).

    pip install pansys

The module assumes that you have ANSYS already installed in your machine. Also, the default command that the module is using is ansys150. You can override it with the start_command keyword argument.

    a = Ansys(startcommand='my_ansys_command')

If you want to change the default start command from ansys150, you can set an environment variable PANSYS_STARTCOMMAND. The value of this environment variable will be used as the start command. This value will be overridden if you explicitly call Ansys session with a startcommand.
