Under Host Entry, I Enter the Hostname and Username for the second node. Now I click on add. It shows up in the Available Hosts list. I select the new Node and click on spawn."

3. Define -> User Defined -> Functions -> Compiled

I follow the entire procedure outlined in the pdf file for the tutorial. So far, so good!

4. Solve -> Iterate

I get the error message concerning mpt_read.

Updating solution at time level N... done.
iter continuity u-water u-air v-water v-air k epsilon uds-0 uds-1 uds-2 uds-3 uds-4 uds-5 vf-air time/iter

999999 (mpsystem.c@1210): mpt_read: failed: errno = 104
999999: mpt_read: error: read failed trying to read 4 bytes: Connection reset by peer
EOF on stderr. The fluent process could not be started.

----------------------------------------

It is these last three lines that are rather confusing:

Such error messages are very difficult to interpret. Only developers can make sense out of it. From a wild guess, I would say this has something to do with the MPI, but I am not sure. What is your opinion?

Additionally, I am able to run the Fluent Parallel Tutorials and their cases from the Fluent website using this setup.

But as the same case runs in Serial very fine on my machine, I admit, I am quite confused.
Please advise.

Any help is appreciated!
