[swanmodel-users] Request: errors in SWAN software and the way to solve it?

[amir s. <ami...@ya...>]

My name is Amir Siahsarani and I am a student at Islamic Azad University, Science and Research Branch, Tehran, Iran. I am using SWAN to run my simulations, however, I have been facing some problems!

Basically, my domain has four boundaries, however, just one of them is open (South boundary). Since I am trying to run my program in Non-Stationary Mode with space-varying wave conditions, I want to use TPAR files within 19 points of open boundary in my simulation for the description of boundary condition.   

I have defined BOUndspec’s command as mentioned below:

BOU SHAPE PM PEAK DSPR POWER

BOUndspec SIDE S CCW VARiable FILE 28.0 'TPAR.txt' 19

I have defined “TPAR.txt” as mentioned below:

SWAN     1          Swan standard spectral file, version

$ Data produced by SWAN version 41.20

I have defined for example “boundaryS1.bnd” as mentioned below:

TPAR

 20070515.060000 0.29 4.98 175.13   2

 20070515.180000 0.30 5.04 174.41   2

…

However, I have faced with the error displayed below:

read error in boundary condition file E:\SWAN\Arabiansea\Prestorm\TPAR1.txt

If you help me find the solution, I will be grateful.
