Hi,

I have a new setup that I am trying to get Flent gui to run, so I may view test output files.  The setup is Cygwin environment running on Windows 10.  Cygwin definition copied below from Wikipedia.  I have all the packages installed successfully, but I get this output when trying to launch the gui:
CKlats000@HQSWL-c029872 ~
$ flent --new-gui-instance
Started Flent 1.2.2 using Python 2.7.15.
font search path ['/usr/lib/python2.7/site-packages/matplotlib/mpl-data/fonts/ttf', '/usr/lib/python2.7/site-packages/matplotlib/mpl-data/fonts/afm', '/usr/lib/python2.7/site-packages/matplotlib/mpl-data/fonts/pdfcorefonts']
generated new fontManager
Initialised matplotlib v2.2.4 on numpy v1.11.2.
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-CKlats000'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

I am thinking maybe it is just some environment variable that needs to be set, but not sure which one.  Any suggestions?

+++++++++ Cygwin environment summary+++++++++
Cygwin is a POSIX-compatible environment that runs natively on Microsoft Windows. Its goal is to allow programs of Unix-like systems to be recompiled and run natively on Windows with minimal source code modifications by providing them with the same underlying POSIX API they would expect in those systems.

This is probably because you haven't started the X server. See
https://x.cygwin.com/docs/ug/using.html

Hi Toke,

Got it.  Started the X server, then I was able to launch flent --new-gui-instance

Thanks!
