To fix, uninstall PyQt4.
OSX:
sudo conda uninstall pyqt
Linux/VM:
cd ~/../../opt/moose/miniconda
sudo ./conda uninstall pyqt
If you see an MPI error like this one (obtained on a Mac) when running a moose or redback simulation:
Fatal error in MPI_Init_thread: Other MPI error, error stack:
MPIR_Init_thread(498)..............:
MPID_Init(187).....................: channel initialization failed
MPIDI_CH3_Init(89).................:
MPID_nem_init(320).................:
MPID_nem_tcp_init(171).............:
MPID_nem_tcp_get_business_card(418):
MPID_nem_tcp_init(377).............: gethostbyname failed, boquier-ri (errno 1)
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= PID 42430 RUNNING AT boquier-ri
= EXIT CODE: 1
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
A working solution (even though not the best or cleanest, so please help improve if you can) is to edit the file /etc/hosts (sudo vi /etc/hosts) and replace the name localhost in the line 127.0.0.1 localhost with the name of your machine, which you can find in the error message displayed above (in my case boquier-ri). In practise you should keep the line and simply comment it with a # sign, giving you the following content
(...)
#127.0.0.1 boquier-ri
127.0.0.1 localhost
(...)
This bool can be true or false. It is used in materials, kernels, boundary conditions, postprocessors. It has to be turned on for running NS simulations on a displaced mesh. It has to be turned off to run simulations of mechanics (using displacement as main variables).
WHY ?
Running Redback in debug mode is useful to debug some issues.
- The starting page to learn about running Moose in debug mode is http://mooseframework.org/wiki/MooseExamples/Example_21/
- You might want to go through a LLDB tutorial (e.g. https://lldb.llvm.org/tutorial.html)
