At the moment I am setting a super high nr of iterations to avoid this, not sure if there is a better way please…?Īnswer 3, I actually deleted the case on both machines and re-ran from scratch and results this time matched, so all good. log files, etc, but this string in OF, so I found it great, in case you need to delete the case and don’t want to input all again from zero every time.įor answer 2, Theodore, thank you, I only don’t know how to override the nr of iterations, as what I care is the residual error, so I don’t want BF to stop at the iterations, if the residual erors have not reached the level I want. ![]() This doesn’t require to set anything, e.g. “< cat simpleFoam.log | grep ‘Solving for p’ | cut -d’ ’ -f9 | sed -n ‘p N N’ | tr -d ‘,’” title ‘p’ with linesīy deleting the “set logscale y” you get a similar graph for the non logarithmic values, if you want to match the graphic style. “< cat simpleFoam.log | grep ‘Solving for k’ | cut -d’ ’ -f9 | tr -d ‘,’” title ‘k’ with lines, “< cat simpleFoam.log | grep ‘Solving for epsilon’ | cut -d’ ’ -f9 | tr -d ‘,’” title ‘epsilon’ with lines, “< cat simpleFoam.log | grep ‘Solving for Uz’ | cut -d’ ’ -f9 | tr -d ‘,’” title ‘Uz’ with lines, “< cat simpleFoam.log | grep ‘Solving for Uy’ | cut -d’ ’ -f9 | tr -d ‘,’” title ‘Uy’ with lines, Plot “< cat simpleFoam.log | grep ‘Solving for Ux’ | cut -d’ ’ -f9 | tr -d ‘,’” title ‘Ux’ with lines, Another telltail problem sign is the lack of the DISPLAY environment variable beign set for you. ssh -X -v And look for thespecific message: debug1: Requesting X11 forwarding with authentication spoofing. cd workingDir/butterfly/outdoor_airflow/log which gnuplot does not find the executable, install the package zypper install gnuplot openSUSE yum install gnuplot CentOS apt install gnuplot Ubuntu. Ensure youre ssh client is requesting X11 Forwarding with the -v flag.gnuplot: unable to open display IP a.b.c.d:x.y gnuplot: X11 aborted. Once MobaXterm is running (and the X server is as well), you can then launch Xclients from remote machines to render on your Xserver, which is running on your laptop.So, for question 1, this is the way it worked for me, writing in OF: If gnuplot is ran from a screen command panel, it starts but loading a script returns. It is pulled in anyway by gnuplot-common (gnuplotx11 binary is taken from a. Windows doesn’t come with X built in and thus why you run MobaXterm. Add debug feature to display constraints/validatetrans from Richard Haines. Gnuplot tries to connect to your “X Windows Server” running on your windows machine. So, in your first case, you were using putty to connect to ganymede and then launching gnuplot. This is counter intuitive sometimes and more discussion can be found on the XWindow Wikipedia page When you SSH into ganymede and then launch gnuplot, in that scenario the Xclient is running on ganymede and it is trying to use the X server that runs on your laptop. ![]() How it works (and the associated nomenclature) is different in the pure X case. While this client / server relationship for RDP and X2go are analogous, for pure X it is not. Your laptop is then running the x2go client and your viewing a desktop that is running on the x2go server.Īs Bennet mentioned, the normal login nodes () do not provide x2go, however, the dedicated x2go servers do. ![]() You download an X2go client from their website ( ) and set it up to connect to the X2go Ganymede login node,. This is similar to how X2go works as Sol alluded to. The desktop from the server is then projected on your laptop which you interact with. With RDP you run an RDP client on your laptop and connect to an RDP server. Most people are familiar with products like Remote Desktop from Microsoft (or the RDP protocol in general). ![]() I wanted to clarify a bit how X works and how it compares to X2go.
