But error “sh: 1: gnuplot: not found” has responsed there. Im using Ubuntu 18.04 and openlb-1.3r1. I’ve saw the same topic, but i don’t get it. Thanks for your attention!

Regards Sthavishtha April 13, 2020 at 11:48 am #4920 iJokerifyParticipant Dear Sthavishtha Thank you very much for your attention! I didn’t thought it has to be installed separately. Now i’ve solved this problem. Thank your again. Sincerely iJokerify Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
