Dear Niels,
Thanks so much for providing such a wonderful tool. I am doing some calculations of hydrodynamics around ocean structures, so wave2Foam is really a great toolbox for me. I am trying to install it at FOAM_USER_APPBIN. But after changing all the files-files (for instance, EXE = $(FOAM_USER_APPBIN)/wave2Foam), I got the following error. Code:
SOURCE=relaxationZone/numericalBeach/numericalBeach.C ; g++ -m64 -Dlinux64 -DWM_DP -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3 -DNoRepository -ftemplate-depth-40 -DOFVERSION=171 -I/opt/openfoam171/src/finiteVolume/lnInclude -I/opt/openfoam171/src/meshTools/lnInclude -I/usr/local/include -I/usr/include -IlnInclude -I. -I/opt/openfoam171/src/OpenFOAM/lnInclude -I/opt/openfoam171/src/OSspecific/POSIX/lnInclude -fPIC -c $SOURCE -o Make/linux64GccDPOpt/numericalBeach.o Kind regards, Albert |
Hi Albert
Thanks a lot for the kind comments. I have just tried making a local compilation, and I did not experience any problems. What I can note from your installation is: 1. To preserve consistency you should do LIB=$(FOAM_USER_LIBBIN)/libwaves2Foam and not $(FOAM_USER_APPBIN) as it appears from your log-file. If you have a problem compiling the code, then it is because you have not created the directory /home/tfuwa/OpenFOAM/tfuwa-1.7.1/lib 2. From the log, it seems that all of the utilities are compiled correctly (can you verify that, i.e. by running them?) Only the solver, waveFoam, is not compiled correctly and it is due to a problem with libinterfaceProperties, which is natively OpenFOAM. To narrow down the problem, could you try to compile interFoam in your USER directory. Kind regards, Niels |

Hi Niels,
Thanks very much for your quick reply and your time considering this error. 1, I made the change as you suggested LIB=$(FOAM_USER_LIBBIN)/libwaves2Foam . While I can compile, the error consists. But yes, you are right that utilities(setWaveParameters, setWaveFields) are compiled successfully and can be run. Code:
tfuwa@tfuwa:~/OpenFOAM/tfuwa-1.7.1/applications/waves2Foam$ ./Allwmake Code:
tfuwa@tfuwa:~/OpenFOAM/tfuwa-1.7.1/applications/interFoamTestCompile$ ./Allwmake Code:
Kind regards, Albert |
Hi
I suspect that it might be a problem with the solver-source. I have based it on OF-1.6-ext, however, I have never myself compiled it on 1.7.1, but one of my former colleagues did. Maybe he did not use my waveFoam but instead modified the interFoam distributed along with 1.7.1. Therefore: Do a Code:
grep "relaxing\|relaxationZone" *C *H Kind regards, Niels |
Hi Albert
I have been talking with my colleagues, and he did indeed base the solver on 1.7.1. material. I will make an update tonight or tomorrow. Unfortunately, I do not have an active 1.7-compilation on this computer. Please accept my apologies for promising 1.7-compatibility. - Niels |
Hi all,
I was having the same compilation error that Albert, and i've found the solution to the problem. If i'm not wrong, you should have installed the OF 1.7.1 Ubuntu (or suse) Pack installed with sudo apt-get ... like i had, and there's the problem, there is some error in the compilated installable pack, because i've downloaded the source pack and compiled it, and then i've compiled wave2foam without any problem! (well, i modified the Make files for install the solver in my USER path...). So try to download and compile a new OF1.7.1, and then compile wave2foam. Hope it works! I also like to congratulate Niels for develop this great tool! Thanks! Jordi. |
Thanks for noting the difference :) I hope you can benefit from my work!

Waves2Foam --> of2+
Niels,
Thanks for all your work on the waves2Foam library and the tutorial on converting interFoam to waveFoam. When compiling on of20x and of21x I had to removed the lines you commented with "//" in src/Make/files. It seems that the dependency tools in the of2+ versions do not like that form of commenting out a line. thanks Dennis |
Thanks for the bug-report. It is actually a shell/OS problem, as some OSs require lines to be commented by /* */ in stead of //.
I will change the SVN as soon as I am at my computer again. Kind regards, Niels |
I did build waves2Foam for of1.6ext with no changes on the same system prior to the of2+ versions. The system is a Rocks + RHEL 5.4 based cluster.
|
Hmm, interesting, as we experienced the problem when moving to another OS.
Good luck with your endeavors with free surface flows. - Niels |
Hi Niels,
It is a great work. I also read your thesis and it is wonderful. Do you have a plan to release the sediment transport module you implmented for your dissertation? Thanks, |
Hi all
@AKA: Thanks. No, we do not have any immediate plans for a release of the sediment transport/morphology module. Its state is by far mature enough. Kind regards, Niels P.S. Forgot to mention that I have updated the waves2Foam/src/Make/files in the SVN. I also made a tiny change in the Allwmake, so if anyone experience problems with that, please tell me. |
Hi all Foamers,
Just wonder is it possible to simulate wave + current with this tool? kind regards, Albert |

Hi Albert
Yes, I have been using it to generate waves+current. In specific I generated stream-function waves with a non-zero stokes drift at the inlet. As I had a beach I modified some source terms and removed the net flux inside the computational domain, however, I think you should be able to use potentialCurrent as an outlet condition, where the target velocity differs from (0 0 0) and instead matches the velocity corresponding to the net flux at the inlet. If you want to have other wave theories, then you must figure out (look up) the mathematical formulation and do the necessary implementation, as I have not done it with any other wave theory than stream function. I hope that this answers you questions. There are some unknowns, but it should be feasible. Kind regards, Niels |
Hi to all
I just got started with waves2Foam (with OF 2.1.0) and I really enjoy it. Thanks a lot Niels! Just a few minor comments: - It looks like in the "squarePile" tutorial there is no p_rgh.org which is needed in 1.7 and later versions. I just copied the pd.org, I hope this is ok. - In the "periodicSolitary" tutorial I had to run foamUpgradeCyclics before Allrun. - Compiling with 2.1.0: I got the following compiler error: Code:
In file included from ./../../../../src/lnInclude/relaxationScheme.H:64:0, - fvSolution in 2.1.0: I replaced Code:
PISO Code:
PIMPLE Have fun Silvan |
Hi Silvan
Thanks. I have added the missing file from squarePile into the repository. I will keep the other changes in mind, when I make a proper 2.0/2.1 supported version. I hope that you can survive with the manual labour until further notice. / Niels P.S. Yes, the lines in waveTheory.H is needed for 1.5 support. Similar lines are also scattered around in the utilities. However, it does surprise me that you get that error, as you are the first one to report it, even though other people have successfully compiled on 2.0/2.1 (one of my students included). |
Sorry about the compiling error, that was my fault. In solvers21/waveFoam/make/options I had
Code:
-DOFVERSION=2.1 \ Code:
-DOFVERSION=21 \ Code:
-DOFVERSION=$(WM_PROJECT_VERSION_NUMBER) \ Silvan |
Dear Niels,
Thank you! This is great for both ship still water resistance using the relaxation zone and sea keeping. The relaxation method is much more effective than the numerical beach I was using before. I've managed to compile it on OF 2.1.0 after some effort and it runs great. I was playing with a test case using the potential current BC with relaxation zones with a non-zero velocity and noticed that the setWaveField command sets the air phase velocity to 0 while the water phase is correct. I noticed that it also does this in the square pile tutorial. Obviously for a moving ship the air speed should be non-zero. Is this a built in attribute or can the user change the velocity of the air to be something other than 0 ? I was hoping to eventually be able to model following seas while the ship is undergoing forward motion and a non-zero air velocity would help with startup stability. Is the setWaveField command necessary to initialize the relaxation zones? Dave |
