I am getting this error after I try to open fluent on ubuntu

"Host spawning Node 0 on machine"

[George Karnos]

This is not an error. this is a message stating that the program is launching on the machine.
If it does not proceed, first thing I would look at is the prerequisites.
Make sure ALL are installed.

Is there more information in the console window? right-click in console window and then choose
select all. once highlighted, right-click again and choose copy. Then paste the info here.

Hello
try these settings in Fluent launcher
in fluent Launcher click on more options >> then go to parallel settings tab >> under mpi types select openmpi

or if using command line then add “-mpi=openmpi” without the quotes to the command line

hope this helps
