[Neeraj Chaudhary]

Dear sir ,

                i am  runing fds job on hpc cluster with pbs job scheduler . But every time the job got terminated after 2 minutes only . it exited with an error .  i have attached the job script , output.log   and error.log file . Plz tell me exact way to run fds job for fast simulation..

First, run the case with the latest version of FDS, either the official release of 6.8.0 or the latest nightly build. If it still fails, submit the input file to the Issue Tracker.

You've got at SIGSEGV (174) error.  Chances are this is a stack size issue on the cluster nodes.  Check with your administrator.  And check to see if FDS has been verified on the cluster.

Have you set your stacksize to unlimited? (https://github.com/firemodels/fds/wiki/Installing-and-Running-FDS-on-a-Linux-Cluster)

Your input file has only one MESH, but you are trying to run the job using two MPI processes. I am surprised it even started. You should not use more MPI processes than meshes.
