Hi there,
I am new to run fluent 18.0.0 in linux debian. I have installed fluent 18.0.0 on the machine with user account, and set up ssh no password. but when I run the command below:
fluent -g 3d -t4

It ends up with the following output:

/home/dawei/fluent/v180/fluent/fluent18.0.0/bin/fluent -r18.0.0 -g 3d -t4

The fluent process could not be started.

if "3d" was typed here, a fluent without parallels can be launched. I don't know what is wrong with mpi!?
