qd.cae.beta¶

Module for CAE stuff related to software from Beta CAE Systems.

MetaCommunicator¶

class qd.cae.beta.MetaCommunicator(meta_path=None, ip_address='127.0.0.1', meta_listen_port=4342)¶

Constructor for a MetaCommunicator

Parameters

meta_filepathstr: optional path or command for the META executable
ip_addressstr: ip-adress to connect to. Localhost by default.
meta_listen_portint: port on which meta is listening (or in case of startup will listen)

Notes

The constructor checks for a running and listening instance of META and connects to it. I there is no running instance it will start one and will wait for it to be ready to operate. If META has to be started, either provide a filepath or simply set the environment variable META_PATH to the executable.

Examples

>>> mc = MetaCommunicator() # starts META , if not listening
>>> mc.is_runnning()
True
>>> # Send arbitrary Meta commands ... hihihi
>>> mc.send_command("read geom auto path/to/file")
>>> mc.show_pids( [11,12,13] ) # show only 3 pids
>>> mc.hide_pids() # hide all
>>> mc.show_pids() # show all

Methods

`hide_pids`
`is_running`
`read_d3plot`
`read_geometry`
`send_command`
`show_pids`

__weakref__¶: list of weak references to the object (if defined)

hide_pids(self, partlist=None)¶

Tell META to make parts invisible.

Parameters

partlistlist(int): list of pids

Notes

Hides all pids by default. If partlist is given, META performs a hide command for these pids.

Examples

>>> # hide two pids
>>> mc.hide_pids( [13,111] ) 
>>> # hide all pids
>>> mc.hide_pids()

is_running(self, timeout_seconds=None)¶

Check whether META is up running

Parameters

timeout_secondsint: seconds of waiting until timeout

Returns

is_runningbool: True if META is running. False otherwise

Examples

>>> mc = MetaCommunicator()
>>> mc.is_running()
True
>>> # Pretty unfunny here, but I actually closed META now
>>> mc.is_running()
False

read_d3plot(self, filepath)¶

Open a d3plot in META and read geometry, displacement and plastic-strain.

Parameters

filepathstr: path to d3plot result file

Examples

>>> mc.read_d3plot("path/to/d3plot")

read_geometry(self, filepath)¶

Read the geometry from a file

Parameters

filepathstr: path to the result file

Examples

>>> mc.read_geometry("path/to/result/file")
>>> # yay we see in meta some geometry ... but not here

send_command(self, command, timeout=20)¶

Send a command to a remote META

Parameters

commandstr: command to send to META
timeoutint: timeout to wait until the command finishes

Notes

The commands send over to META are identical as if they would be typed into the command line window.

Examples

>>> mc = MetaCommunicator()
>>> mc.send_command("read geom auto path/to/file")
>>> mc.send_command("add pid 4,5,3")

show_pids(self, partlist=None, show_only=False)¶

Tell META to make parts visible

Parameters

partlistlist(int): list of pids
show_onlybool: whether to show only these parts (removes all others)

Notes

Shows all pids by default. If partlist is given, META performs a show command for these pids. If show_only is used, all other parts will be removed from vision.

Examples

>>> # show all pids
>>> mc.show_pids()
>>> # make two pids visible
>>> mc.show_pids( [13,111] ) 
>>> # let's show only two pids
>>> mc.show_pids( [13,111], show_only=True)
