[swanmodel-users] Issue with Running SWAN Using MPI

[Ali A. <sra...@gm...>]

Dear SWAN Users,

I hope this email finds you well. I am currently working on a project using
SWAN version 41.45 on Ubuntu 22.04, and I have encountered an issue when
trying to run SWAN using MPI.

Here are the details of my setup and the problem I am facing:

System Specifications:
CPU: Intel(R) Core(TM) i7-4720HQ CPU @ 2.60GHz
Operating System: Ubuntu 22.04
Fortran Compiler: gfortran (GNU Fortran (Ubuntu 11.4.0-1ubuntu1~22.04)
11.4.0)
MPI Implementation: OpenMPI 4.1.4

SWAN Input File:

Command Used:
bash
*mpirun -n 2 ./swan.exe*
Output/Error Message:




*SWAN is preparing computationAbort(4) on node 0 (rank 0 in comm 0):
application called MPI_Abort(MPI_COMM_WORLD, 4) - process 0Both the
printfile and Errfile are empty.*

Additional Information:
The input files *Bathymetry2.bot* and *Boundspec1Dnr.txt* are located in
the Input directory with appropriate permissions.
I have verified that the paths in the input file are correct.
SWAN is Installed correctly in mpi mode.
Request:
I would greatly appreciate any guidance or suggestions to resolve this
issue. If anyone has encountered a similar problem or has insights into
what might be causing the MPI execution to abort, please let me know.

Thank you for your time and assistance.
