To whom it may consern, I have a Problem with the current Input using the Manual Settings in SwanOne VERSION NUMBER 41.20. The file is read correctly during the Input. SwanOne Shows the right Course in the x-x or y current Speed diagram, but later the projectname_U.DAT file does not Show the Right current Speed for the direction parallel to the one of the Depth profile. I will send you the Project files, too. Would be great if you can check this? Here another Question regarding the user Manual: The explanation of the current Input file is a Little missleading, because there is written that the second column is for the current Speed parallel to the Depth profile in offshore direction, but the scetch next to that Shows the positiv Speed in direction to the coast. Which direction is the positiv one? Thank you for your time.

Hello Sara, ST6 was observational-based physics, the wind drag coefficient is different from other physics. Have you looked at the original work on the implementation of ST6 in SWAN ( https://journals.ametsoc.org/doi/pdf/10.1175/JTECH-D-11-00092.1)? The drag formulation is EQ.15 which basically depends on the wind speed (U10). So, if you use ST6, your calibrating parameters are all located in one line as you have specified: GEN3 ST6 5.7E-7 8.0E-6 4.0 4.0 UP HWANG VECTAU TRUE10 Normally, you can play around with two parameters (highlighted as red) to see the difference. Also, see page 56-58 in SWAN manual for the use of ST6 in SWAN. Best of luck!

Hello! I am recently working with SWAN and currently am modeling scenarios of tropical cyclone winds but I've got a question to which hopefully advanced users may be able to answer. The model setup I'm working on includes a wind drag coefficient with the recommended value (cdcap=2.5× 10−3) since the model is forced with intense wind speeds (over 120km/h). Also there is no wave input. The physics commands that I have implemented are: triads, whitecapping, quadruplets, bottom friction, wave breaking and a third generation model GEN3. The model runs correctly but I have found that the results of significant wave height maps are the same using either cdcap=2.5× 10−3 or with no cdcap. This is what struck me the most, since the cdcap seems to have no effect at all, and I am beginning to consider whether there is any requirement/command that needs to be implemented as well in the setup model?? I would appreciate it very much if anyone could give me some insight in this matter. Many thanks in advance! Sara Here follow the commands a was referring to earlier from the input.swn: $ MODE NONSTAT COORDINATES SPHER CCM SET level=0 cdcap=0.0025 NAUTICAL $ ... $ WIND DRAG WU GEN3 ST6 5.7E-7 8.0E-6 4.0 4.0 UP HWANG VECTAU TRUE10 QUAD iquad=8 WCAP BREA FRICTION JONSWAP $ TRIADS PROP BSBT |

Hi Sandhya, Sorry about my delay as well... Apparently the ascii files are OK in terms of size. The .mat file, however is a bit big (approx. 1 GB). It still shouldn't be a problem, depending on how the filesystems are set in your HPC machine and how the files are being put together. Basically, if you have a single filesystem that is exported to all the nodes, the output files will all be saved at the same filesystem (or place) and they can be handled as if they were all in a single (local) drive by the node that is assembling the results. Now, if your nodes are saving the results in their own local drives, all the information will have to be copied through your HPC's network before they are merged together, so that is where your bottleneck might be. **However, I am not 100% sure!!** Talk to your HPC's admin, check whether you have a shared filesystem through all your nodes and if so, set SWAN's output to that filesystem... And let's see what happens. Good luck, João On Wed, 28 Aug 2019 at 22:13, Sandhya K G <san...@in...> wrote: > Hello João, > > > Apologies for the delay in replying.

Dear all, I am running a simulation with an UNSTRUCTURED grid and activated constant mud command But as the mud thickness and other features changing in the area, I need to input mud in a grid I have a problem that I don't have an example that how the input file should be. I'm asking if someone could send me a Mudlayer inpgrid file example thanks in advance for your kind answers. Best Regards, Fatemeh Ameri |

Dear all, I am trying to save spectral output from ADCIRC+SWAN at one location. But it is showing error. My saved specout file contains only initial details about frequencies and the time steps but no data. Depth at the saved locations is also perfect. What could be the error?

Hello João,
Apologies for the delay in replying. Somehow I missed your mail.
I am requesting point outputs and 1D spectral outputs at 8 locations with TABLE and SPECOUT commands. Also requesting spatial output in .mat format.
Sizes:
TABLE o/p : 12099 kb each
1D spectra: 83675 kb each
.mat file: 1090643744 kb
Since I am using unstructured SWAN in mpi the outputs are formed in individual PE???? directories and combined automatically at the end of model run. I am presently using 16 nodes (16 processors each)-total 256 processors.
Regards,

Hello Sandhya,
Could you please provide more details on what you're doing? I.e., number and type of output points, average size of each output file (mat and ascii), method you're using to put the files together, etc?
Are all the files stored at the same shared file system or are they in different file systems (locally created on each computing node)?
Best,
João

Hi,
I am running unstructured SWAN model in mpi mode in HPC machine.
Though the model run is very fast (10-15 minutes), it takes 1-2 hrs for combining the output (.tab files/spectra files/spatial output .mat) files. If I use more processors, the model run is still faster, but it takes still more time to combine the outputs from different processors.
Is the I/O operation a single processor job?
What is the wayout for completing the whole process in lesser time?
Regards,

Hello Sandhya, Could you please provide more details on what you're doing? I.e., number and type of output points, average size of each output file (mat and ascii), method you're using to put the files together, etc? Are all the files stored at the same shared file system or are they in different file systems (locally created on each computing node)?

Hi,
I am running unstructured SWAN model in mpi mode in HPC machine.
Though the model run is very fast (10-15 minutes), it takes 1-2 hrs for combining the output (.tab files/spectra files/spatial output .mat) files. If I use more processors, the model run is still faster, but it takes still more time to combine the outputs from different processors.
Is the I/O operation a single processor job?
What is the wayout for completing the whole process in lesser time?
Regards,

Hi, I was wondering if someone could explain to me the difference between RTpeak (relative peak periode) and the peak of the energy density spectrum? To give more content to my question I have attached some files. As you could see from the .tab file I have attached, the highest RTpeak is 5.7403s. >From the .png file one can see that the peak for the energy density (kg/s) is around 0.125 - 0.140Hz which is between 7 and 8s. Does this mean that the peak period is between 7 and 8 s, and the relative peak period lower due to influences of wind currents* that are generated in the swan simulations? *From what I have understood, relative peak period (E(sigma)) equals the absolute peak period in the absence of currents. Where the relative peak period is related to the absolute maximum bin of the discrete wave spectrum and hence, might not be the "real" peak period (http://swanmodel.sourceforge.net/online_doc/swanuse/node35.html).

Hi Anjali, Using your U/V values below, I get 149.7572 degrees for the wind direction (towards which the wind moving). The wind in this case is from 329.7572 degrees. The U/V components in ERA5 are vector components that are considered to-which as well.

Hi Alex,
Thank you sir for your reply. The wind input I gave in SWAN are u
and v files obtained form ERA5. I have calculated the direction also, to
know how much difference exist between wind direction and wind input
direction. For u=6.11 and v=-10.48, the calculated wave direction is
329.73. Hope this calculation is right. Kindly let me know if my
calculation is wrong.

Hi Anjali, It sounds like a mismatch between the conventions of the directional grid and the ERA5 wind direction you are using. Did you compute wind direction yourself from U and V components of wind speed or did you obtain it pre-computed? It sounds like the provided wind direction is "from-which" (a standard meteorological convention). I forget SWAN's directional convention for waves, but I think it is "towards-which".

Hello Zoulikha, This is the beginning of a wind file for nonstationary winds. The commented information (preceeded by a #) is not necessary, however it helps you check whether your file is OK or whether SWAN is reading it properly. This wind grid file is defined in the .swn file as follows: $ wind input definition INPGRID WIND REG 163.1250 -49.7271 0 13 14 1.40625 1.38903 NONSTATION 19930101.000000 3 HR 20051231.210000 $ wind input data reading READINP WIND 1 SERIES '1993010100-2005123121.lst' 3 2 1 1 FREE As you can see, I am using a file (1993010100-2005123121.lst) that indicates where and which are the files containing the wind information.

In my case I am creating these files with 6 months of information each. You can have files with more or less data (i.e., dates). However I wouldn't recommend having one single file for each wind grid as this can cause you problems while running SWAN in nonstationary mode. Have a careful look at the manual, the definition I used and the file so you can understand what is going on, assuming that this is what you are looking for.

Hi everyone I am new to this swan setup although I have previously use Delft3d wave. I like to transfer the same grid (Regular) into acceptable SWAN format. is there any method to do so or any other suggestion to make the grid for SWAN. I need an open-source solution. Thank you for your time Regards Subhajit |

Hi, You can easily extract data from netCDF files using the NCO software (http://nco.sourceforge.net/). NCO includes multiple tools, but you'll be interested in ncks. Read the ncks docs (http://nco.sourceforge.net/nco.html#ncks-netCDF-Kitchen-Sink) and you'll be able to extract the desired data from an specific area using the [-d] option. Best, Javi |
