Hi,
I installed PyFoam 0.6.9 using pip. Problem is, the path to the gnuplot installation is wrong hence the residual plot cannot be displayed. I get the following error message: Expected X11 driver: /usr/lib64/gnuplot/gnuplot/5.2/gnuplot_x11 Exec failed: No such file or directory See 'help x11' for more details Expected X11 driver: /usr/lib64/gnuplot/gnuplot/5.2/gnuplot_x11 Exec failed: No such file or directory See 'help x11' for more details I tested both programs and both work fine independently. I also checked an older Ubuntu installation and in both cases, Ubuntu and my new Linux installation, gnuplot is installed in the /usr/bin /usr/share/gnuplot /usr/share/gnuplot/5.2 or /usr/lib/gnuplot directories. How/Where can I adjust the path to gnuplot in PyFoam 0.6.9? The workaround I tried is: 1: Create the expected folder structure /usr/lib64/gnuplot/gnuplot/5.2/gnuplot_x11 2: Create a symbolic link to gluplot 3: Now I had to create SSL certificates And got the following errors: gnuplot> BSR ^ line 0: invalid command gnuplot> X -1 1 1 -1 -1 ^ line 0: invalid command gnuplot> X -1 1 1 -1 -1 ^ line 0: invalid command gnuplot> BSR gnuplot> BSR ^ ^ line 0: invalid command line 0: invalid command gnuplot> BSR gnuplot> X 0 1 1 -1 -1 gnuplot> X -1 1 1 -1 -1 ^ ^ ^ line 0: line 0: invalid commandinvalid command line 0: invalid command gnuplot> X 0 1 1 -1 -1 gnuplot> X -1 1 1 -1 -1 gnuplot> X -1 1 1 -1 -1 ^ ^ ^ line 0: invalid command gnuplot> BSR line 0: invalid commandline 0: invalid command gnuplot> BSR gnuplot> X -1 1 1 -1 -1 ^ ^ ^ line 0: invalid command line 0: gnuplot> X -1 1 1 -1 -1 invalid command gnuplot> X 0 1 1 -1 -1 line 0: invalid command gnuplot> BSR ^ ^ ^ line 0: invalid command line 0: invalid command gnuplot> npyFoam: Bounded variables gnuplot> X 0 1 1 -1 -1 line 0: invalid command ^ gnuplot> X 0 1 1 -1 -1 ^ line 0: invalid command ^ line 0: invalid command gnuplot> X -1 1 1 -1 -1 gnuplot> BSR line 0: invalid command ^ ^ gnuplot> X 0 1 1 -1 -1 line 0: invalid command line 0: invalid command^ gnuplot> X -1 1 1 -1 -1 line 0: invalid command gnuplot> BSR ^ ^ line 0: invalid command line 0: gnuplot> npyFoam: Continuity invalid command ^ gnuplot> X -1 1 1 -1 -1 line 0: invalid command ^ gnuplot> X -1 1 1 -1 -1 line 0: invalid command ^ line 0: invalid command gnuplot> npyFoam: Residuals ^ line 0: invalid command gnuplot> X -1 1 1 -1 -1 ^ line 0: invalid command Any idea how to fix this?

Which Linux are you using (you stated that your "old" installation was an Ubuntu. The current is just called "new Linux") One frequent problem is that some distros have a generic gnuplot-package that can do no graphics. For plotting windows another package gnuplot-x11 (or similar) is needed. Check if that is the problem in you case

which gnuplot gives me:
/usr/bin/gluplot When I start gnuplot, gnuplot> plot sin(x) shows the expected graph on screen. When I use "gnuplot as a function" and enter: gnuplot '-p -e sin(x)' directly in the terminal, the parameter -p is required to get the same result. Without -p, the graph is just showing up for a fraction of a second. Terminal type is 'wxt' |

I am using the option: --gnuplot-terminal=wxt
The plot starts but the gnuplot errors in the logfile remain. |
