How to launch a file with multiple meshes

[foster...@gmail.com]

Hello,

I am trying to launch a file composed by three meshes. I have followed what is established in the FDS User's Guide (sections 3.2 and 6.3.3) in order to have one mesh assigned to every MPI process.

However, I find that there is an error in the FDS CMD screen saying:

- WARNING: MPI_PROCESS set for MESH 2 and only one MPI process exists

- WARNING: MPI_PROCESS set for MESH 2 and only one MPI process exists

I thing that I have written in my FDS file the correct commands, but something is wrong.

If someone could help me with this issue, I'd be grateful.

Cheers.

I want to launch this simulation on my single PC, where I have 8 cores.

Cheers.

On windows the fds command is:

fds_local -p x -o y job_name.fds

where x (default=1) is the number of MPI processes and y (default=4) is the number of OpenMP threads.  

Your screenshot is suggesting that you did not set -p and -o and are just seeing the default values.

Thank you Mr Floyd,

However, I have specified that I have 3 MPI processes and 2 Open threads, so that I will exploit 6 cores. Therefore, why do I receive this warning, if I have correctly specified that information?

Cheers.

The image you attached does not show the command you typed. What exact command did you type at the prompt?

In my first message I attached the FDS file, where all the commands can be read.

To run fds you started FDS_CMD to get a command prompt. At that command prompt you then typed a command to run fds.  What command did you type?

Hello Mr Floyd,

I attach a screenshot of what I have typed in my FDS command.

Cheers.

That is not the command given in Section 3.2 of the User's Guide under the subheading of MS Windows.
