Error in GNUplot & image data

[achodankar]

Hello,
I have run the cylinder2d example. I can see the .p, .matrix, and .dat files in the GNUplotData and imagedata folders. However, it doesn’t show the png/jpeg or pdf files generated by GNUplot.

The following error shows up in the terminal window after compiling & running the code:

1) First error

set terminal png size 1920,1080font “,25”;
^
“./tmp/imageData/data/heatMapquality.p” line 3: unknown or ambiguous terminal type; type just ‘set terminal’ for a list

2) Second Error
set terminal pdf enhanced
^
“./tmp/gnuplotData/data/plotPDF.p” line 2: unknown or ambiguous terminal type; type just ‘set terminal’ for a list

I would really appreciate any help on this matter.

Thank you.

Yours sincerely,

Abhijeet

Hello,
I was able to run the .p scripts using gnuplot-x11 and get the corresponding images and pdfs. However, I had to do all of it manually. How should I modify OpenLB code to use gnuplot-x11? I have uninstalled the gnuplot version, so I just have the gnuplot-x11 version presently.

You can change the gnuplot command in src/io/gnuplotHeadMapWriter.hh:247 respectively src/io/gnuplotWriter.hh:337. For your example the latter should be the relevant one.
