I am a student studying at Korea.

I have simulated using delft3D-FLOW.

Recently, I am trying to simulate a storm surge using Delft3d FM.

I have a simple question.

When I enter the Spider Web grid file on FM, can I use the .spw file using the dashboard?

Does delft3d-FLOW and FM use the same spider web grid file (spw)?

and How do I set the atmospheric pressure in FM?

Average air pressure on bounds/ average initial air pressure are 0 N/m^2 or 101325.00000 N/m^2 ??

Please answer a simple question.

I always thank you, guys.

Thank you.

d-flow fm bug

We have been running annual simulations roughly August-to-August, and with a new model setup the runs get stuck around Dec 1. I believe this is due to this snippet of unstruc.F90, line 12184 in unstruc.F90, rev50237, part of inctime_split. As far as I can tell, newer versions of unstruc.F90 have the same code here.

2    case ('M')
3           imonth = imonth + ti_split
4           if (imonth > 12) then
5               imonth = mod(imonth, 12)   ; SWAP
6               iyear = iyear + floor(real(imonth)/12.0) ; SWAP
7           end if

Switching the order of the 'SWAP' lines allows the runs to continue, at least in our limited testing so far. Please let me know if I'm missing something. If this is not the correct fix, then perhaps we can post more details of our simulations for some help on figuring out the source of them getting stuck.

Dear Rusty,

Thank you very much for reporting this bug. It is correct to exchange the two lines as you mentioned. We have also corrected the bug in codes of DFlow FM.

With kind regards,
