[swanmodel-users] Installing SWAN using Mac Terminal w g95

[Veronique B. <ver...@gm...>]

Hello all,

I am experiencing some problems setting up my terminal to be able to run
SWAN. I have a 2016 Macbook updated to Big Sur, and have command line tools
installed. When I open a terminal on the swan4131 folder, and try to enter
in the "make config" command, it says that my current Fortran compiler,
"g95" is not supported. Has someone had this issue before? I am hesitant to
use this code: "gfortran -c source.f90" because I do not want to create any
new folders I don't need to. Is there a way for me to use the g95 compiler
I have to run SWAN?

Thank you,

Veronique

Re: [swanmodel-users] SWAN 41.31 OpenMPI error

[Joao A. <ja...@au...>]

Hi Javi and Clemens,

One thing to consider is that nowadays it is very common to have a large
number of cores inside a single cluster's node. Which means that,
particularly for SWAN, OMP will do the trick for you.

For example, in the first cluster I worked with SWAN, I had 24 cores per
node while in the present cluster I have up to 36 cores per node available.
The benchmarks I ran back then showed little benefit in using more than 24
cores and MPI in the old cluster. So, possibly, it is more efficient
(memory wise) to run SWAN distributed along the cores of a single node than
spreading it through the nodes of the cluster. I never ran these benchmarks
with the new cluster though.

Your mileage may vary, of course. But based on the little experience I had,
you shouldn't be too bothered about using SWAN with MPI. In any case, if
you manage to use MPI, I'd be more than happy to learn from your results.

Best,
João

Re: [swanmodel-users] SWAN 41.31 OpenMPI error

[Javi R. <ja...@pr...>]

Hi Clemens,

II would try to do the following:
1. Compile SWAN in serial mode, and try to run the model.
2. Compile SWAN in OMP mode, and try yo run the model.

If that works, then try to build SWAN with MPI instructions.

Take a look at this guide I wrote some time ago about building SWAN:

https://gitlab.com/javier.rodriguezg/swan-support/-/blob/master/recipes/build_linux.md

[swanmodel-users] SWAN 41.31 OpenMPI error

[Clemens K. <Cle...@tv...>]

Dear all,

I recently compiled SWAN for my Linux system (Pop!_OS 20.04) without any 
big issues and could run the test files flawlessly.

Now I finished setting up my own SWAN model, but somehow I am not able 
to run it on my system as I always get a MPI error, which is as follows.

Invalid MIT-MAGIC-COOKIE-1 key
  SWAN is preparing computation

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 4.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

--------------------------------------------------------------------------

Same holds true for a colleague model. He is however, able to run my 
model on his system. I compiled the system using GCC 9.3.0 and Open MPI 
4.0.3.

Thank you for your help in advance.

Best,
Clemens

Re: [swanmodel-users] How to export Swell direction and period in SWAN

[joao de a. <j.d...@au...>]

Hi Ngoc,

Adding to Huy's message, swan can provide you the swell wave height if you
use the output parameter SWELL in your BLOCK command. However it is only
the swell wave height considering a frequency threshold separating
wind-seas and swells.

Another possibility is to use PTHSign, PTRTP and PTDIR among the other
partitioned outputs SWAN can provide. But still, in this case SWAN will
provide you with 10 partitions (not all of them used, of course) and you
would have to aggregate the swell partitions if you are interested in only
one swell.

Have a look at the output options of the BLOCK command and in the
definition of the variables in App. A.

Best,
João

Hi Ngoc,

If you have wave spectral outputs, you can do partition of directional wave
spectra: https://github.com/gvoulgaris0/WavePart

Dear SWAN users,
Now I want to export Swell/ Wind wave direction and period in SWAN but I do
not see these parameters in SWAN. However I see names of period that have
the same meaning (like TM01, PER, TMM10 which mean absolute wave period (in

Could you please explain for me about what is different between these
parameters?
How can I export  Swell/ Wind wave direction and period in SWAN?

[swanmodel-users] Please help with a parallelization issue with SWAN model

[Zhu, L. <l....@no...>]

Hi,

I encountered an interesting issue with SWAN model.

I got different results using different cores. I ran the model on HPC (machine configuration: 1 processor contains 20 cores). I have tested 80 cores, 160 cores, and 200 cores.
The 80-core and 160-core results are similar, but there are obvious missing data in 160-core results. The 200-core results are completely wrong.

I didn’t find related information online. I am wondering whether you could provide insights on this issue. Thanks a lot.

Best,
Ling Zhu

[swanmodel-users] source code SWAN 40.72

hey swan users,
I'm using SWAN 40.72AB version on my personal computer,

Re: [swanmodel-users] differenze per il cambio versione, da 40.72 a 41.3

[João A. <ja...@au...>]

Hi Giullia,

By comparing Appendix C of both manuals, it is possible to see the changes
in the physics of both versions, as well as the default options. If you are
using the same configuration file, whatever you omit will be changed by the
version's default at each simulation.

This is just a first guess and I'm assuming you have exactly the same data
and configuration files in both machines.

Good luck,

João

Re: [swanmodel-users] Error punswan mesh

[Javi R. <ja...@pr...>]

Hi Jose Manuel

It looks like your mesh file (fort.14) has some kind of format problems. According to the warning error you are getting, your vertices are not right. They must be ordered in counterclockwise mode.

If you're running a computer using Windows, you can check your mesh node numbering with a free tool called BlueKenue.

1) run the line:

adcprep --np 6 --partmesh
adcprep --np 6 --prepall

mpirun -np 6 punswan
error appears:

(unit = 4, file = './PE0002/PRINT')
Internal Error: Bad format node

then I check the file, PRINT:

in fort.15, i have:
&subdomainModeling subdomainOn=F /

when use:

i need the file fort.015, but i don't know to create it

Thanks.

[swanmodel-users] punswan slower in parallel (20 cores) than serial (1 core)

[Almir N. De B. J. <alm...@tv...>]

Dear all,


I am trying to use punswan in Linux cluster. But I am having a strange situation.


What is happening is that running the model in a cluster using 20 cpus and it is slower than running this application in my PC using 1 cpu.


I am using the following lines in the SLURM script for calling the application:


export OMP_NUM_THREADS=20

mpirun --np 20 swan.exe


I am suspecting that I am running the application 20 times instead of one time in parallel (I don't know if this makes sense).

I managed to enter the node and execute the top command and I can see that the 20 cpus are being used 100% and 20 instances of my program are running.


Another thing I noticed is that although I have all the 20 PE subdirectories swan is not accessing them.


For allocating the resources I use the following lines in the SLURM script:

#SBATCH -N 1

#SBATCH --tasks-per-node=20

#SBATCH -n 20


I compiled punswan following the Implementation Manual instructions and everything ran apparently well generating the executable.


Any of you have had a similar experience and could give a hint? Any advice is most welcome!


Thanks!

[swanmodel-users] atmospheric momentum fluxes

[Kaihatu, J. M <jka...@ci...>]

Hi –

Does SWAN output the momentum fluxes in the surface layer? I’m guessing it doesn’t. I _think_ (I’m not really familiar) that the Janssen et al mechanism in SWAN uses the momentum fluxes in the surface caused by atmospheric forcing to inform the growth function, but that might be as far as it goes.

Re: [swanmodel-users] change unit of 2d Wave Spectra

[Rafael G. <raf...@ya...>]

 Hi Giulia,
in case that is useful there is some function in wavespectra python library to read spectra from ERA5 format which does the conversion from radians into degrees. Once the spectra is read, it can be easily output in different file formats including SWAN ASCII format which could be directly used to run SWAN.

Hi Giulia,

Yes you are right. Take a look at Appendix D of the user manual, there are some useful example files.

[swanmodel-users] Computational Grid rotations and wave directions

[Osorio M. R. <ro...@ms...>]

Hi SWAN community,

I am a relatively new SWAN and wave modelling user, so my question could be a basic one. I am using the SWAN GUI in stationary mode to compute wave parameters in inland lakes with short fetches and weak winds. In the processes of validating the model,  in general I am getting good results in Hs (in most of the cases), underestimated results for Tm (as common in SWAN) , and bad results for wave direction. I figured out that rotating the computational Grid  improved my wave direction validation results. However, the same angle of rotation does not work for all cases. Hence, I have the following  questions:

  1.   In what should I based the computational grid rotation ? (i.e. incoming mean wave direction)
  2.  Also if I rotate my computational grid, do I need to rotate my incoming wave and wind direction as well?


I have seen in other studies that users generally rotate their grids with the x axis facing the shoreline, but in my case that doesn't apply since my study area is an enclosed pond. Any comments or suggestions are welcome.

Thank you,
Raul Osorio

Re: [swanmodel-users] Long-term WW3 boundary conditions

[João A. <ja...@au...>]

Hi Jin Liu,

I ran SWAN with 20 years of spectral boundary data along 141 boundary
points. Each boundary point file had approximately 1.6G. At first I thought
that having only one set of boundary files was a good idea, however as it
is very hard to get a flawless 20-year SWAN run depending on your output
parameters (not to mention the long time it takes), having single large
files (and less trouble setting up the .swn file) proved to be a bad idea.

By breaking the 20-year simulation into 20 yearly simulations using the
same boundary forcings, SWAN would spend hours of computational time just
reading the boundaries and winds.

Your files are not too bad in terms of size since they already have all the
boundary points you are using. If your concern is writing the .swn files
for all the runs, you can create a script to generate your SWAN files based
on a template swn file.

If you still intend to reduce the size of your files, an alternative would
be to redefine your spectral data into a coarser spectrum, e.g., smaller
number of directional bins and frequencies, as long as it has no effects in
your application.

Best,
João

Re: [swanmodel-users] Long-term WW3 boundary conditions

[Clement C. <cle...@uc...>]

Hi Jin Liu,

I think I ran into a similar problem, I am using WW3 to generate boundary
conditions for my SWAN model and for some reasons that I forgot the
BOUNDNEST commands didn't work very well for me.

What I'm doing now is that I print the output from WW3 at the positions of
the SWAN boundary. It can be spectral station output, or mean station
output, it depends on the shape of the incoming spectrum you are getting on
average, in my case I mostly deal with single peak wave conditions so the
mean parameters are enough, and take less space on the disk.
I then use the following code to rewrite the WW3 output for SWAN and force
SWAN with the BOUND (mean) or BOUNDSPEC (spectral) command.

My code is written in Julia, but if you are using another language it won't
take you long to translate it into python or matlab.

I hope it can help, let me know if it is not clear!
Clement
