I am PLN Murty, doing PhD at IIT Delhi, India. I am trying to implement coupled ADCIRC - SWAN model. I have compiled the code as given in the mannual. While I am executing the model , I am getting error like Segmentation Fault.
I am using the command mpirun -np 32 ./padcswan for running in parallel.
When I give the above command, the following message are displayed which ended with an error (Segmantation fault) message...
I have pasted that below.
SWAN is preparing computation

forrtl: severe (174): SIGSEGV, segmentation fault occurred
rank 16 in job 24 ajaymeru.cas.iitd.ernet.in_46714 caused collective abort of all ranks
exit status of rank 16: return code 174
Can anyone kindly suggest me how to overcome this problem.
Thanks in advance.
