Plotting and Mesh Access

[marj44]

Hello,

I'm trying to run this example but when I try running the following script I don't get the output shown on the website. I am not sure if it's a me issue only. I'm using PyMAPDL v0.61.6. Any help is appreciated.

SCRIPT

import numpy as np
from ansys.mapdl import core as pymapdl
from ansys.mapdl.core import examples
mapdl = pymapdl.launch_mapdl()
bracket_file = examples.download_bracket()
mapdl.aux15()
mapdl.igesin(bracket_file)
print(mapdl.geometry)

OUTPUT

Expected Output:

Current Output:

Looks like you're unable to download the external example file for some reason.

We're basically using requests (REST) to "download" the file. My guess is that you're unable to call out from your computer for some reason. Can you run the following for me?

import urllib.request
urllib.request.urlretrieve("http://www.lancsngfl.ac.uk/cmsmanual/download/file/barnaby-1.bmp", "barnaby-1.bmp")

This should download a simple bmp locally. If this fails, there's something blocking external downloads within your network.

Yeah, I get an error when trying to run the two lines provided.

File "...\request.py", line 1353, in do_open
raise URLError(err)
urllib.error.URLError: <urlopen error [Errno 11001] getaddrinfo failed>

Looks like outbound requests are being blocked.

@germa89, can you provide a workaround (maybe a downloads page) so users that cannot access files via the downloads module can still download files?

@akaszynski

I will think about this. I guess we could wrap everything in a try and if it fails, print a message that all the files are in: https://github.com/pyansys/example-data

If needed, we could add also the download page.
