Hi all,
I tried to run a easy case and met a segmentation fault. So I turned on the USER_DEBUG, the results show belows:
I tried to figured out the problem but still have no idea yet.
Hope anyone have met this problem. Thanks lol

What is on this line?
Oops, didn't see this:at /home/ubuntu/app/COAWST_V3.2/Build/get_data.f90:101
Did you tell it NFFILES before the list of forcing files?Fortran runtime error: Index '1' of dimension 2 of array 'frc' above upper bound of 0

Re: Segmentation fault
Hi Kate,
Thanks for your reply.
I don't want to input any forcing file, so I use '!' to comment out the code, as shown in the figure below. And the problem happend.
Then I delete '!' and change this code to 'NFFILES=0' , but ROMS told me NFFILES must be greater than 1.
I wonder that if it's necessay to input forcing files.
Thanks!

Re: Segmentation fault
Well, you could try submitting a bug report for this case of no forcing files, but most of us just set NFFILES to 1 and move on.

Re: Segmentation fault
Kate
Thanks for your reply, you really help me out! So people usually input at least one forcing file, my case is not common.
By the way, where can I submit a bug report?

Re: Segmentation fault
This is not a bug. It always has to be equal or greater than one by design. If no input forcing files are needed, ROMS will ignore those values on standard input. I don't understand what it is the Fuzz about it. There are a lot of parameters in ROMS standard input that will be only relevant for a specific configuration. If not, they will be IGNORED!
NFFILES is needed to allocate an internal ROMS structure and initialize several parameters even if it is not used.

Re: Segmentation fault
Thanks, I set NFFILES = 1 and input forcing file(though values = 0), it works now.arango wrote: ↑Sat Jan 04, 2020 7:35 pm This is not a bug. It always has to be equal or greater than one by design. If no input forcing files are needed, ROMS will ignore those values on standard input. I don't understand what it is the Fuzz about it.
