Inlet_test with SWAN only under constant wind speed

#1 Unread post by hzh_1211 »

Hi, everyone, I test to run the inlet_test case with SWAN only in the COAWST.
When I used the default input file (swan_inlet_test.in), it runs ok.
But when I add the WIND command, I got the Error information, as follow

Code: Select all

At line 5036 of file swanparll.f90
Fortran runtime error: Unit number is negative and unit was not already opened with OPEN(NEWUNIT=...)

Error termination. Backtrace:
#0  0x14a584f9732a
#1  0x14a584f97ed5

I am a newcomer in SWAN, please give me some advice.
The setting about SWAN input file as follows

Code: Select all

PROJECT 'Inlet Test' ' '
 'INLET test'
 'Bathymetry: flat bottom'
 'COMMENTS'

MODE NONSTATIONARY TWODIMENSIONAL

just got back around to trying this. sorry for the delay.
I get an error, but it says

more Errfile01
Error : Quadruplets should be activated when SWAN

so if i turn quads back on by commenting this line :
&OFF QUAD

then it works. also make sure you have correct paths to the input files. i see you have
READGRID COORDINATES 1 'inlet_test_grid_coord.grd' 4 0 0 FREE
so that file needs to be in the same folder as the executable.
