Thanks for including the file.
You must used a unique label to define the Refinement Box; therefore, you should name it "freesurface" and not "free surface".

Thank you!
Another thing, I think I need to use extrudeMesh after snappyHexMesh because I'll need a 2D case not 3D. How can I do it?

Hi Luis,
(I don't know why I keep calling you Tiago when you don't sign your messages with that name, sorry about that.)

We have not added yet that capability to our GUI;
therefore you should run it in a terminal.

I'm sorry for my first post to be such a basic question but I would really appreciate any help! I'm desperately trying to get the GUI working but can't get any of the tutorials to open (the GUI just shuts down). I'm new to OpenFOAM so finding the learning curve very steep! I've copied the Ubuntu screen if that helps:

Please, use this forum to discuss your issues or talk about the topics that you might find interesting, it was created for this purpose.

I was not able to reproduce your error, can you tell me what ubuntu version are you using?

Best Regards,
IHFOAM Team

[unners]

Thanks for the quick reply! I'm using Ubuntu 16.04 although it is running inside windows 10. OpenFOAM 18.06 seems to be working ok outside of the GUI.

Looking forward to contributing down the track! Thanks. Dave

[IHFOAM Team]

Hi unners,

I had to ask for a laptop with windows 10, then install Virtual Box, then create a virtual machine with ubuntu 16.04 64bits, then download the GUI and run it.... and it works!!!



(Sorry about the poor quality of the picture, I used my mobile phone.)

So, can you checked if you have installed a 32 or 64 bits ubuntu version in your virtual machine?

Regards
IHFOAM Team

[whwngus45]

I don't know to play ihfoam gui blockMesh not found

I replay to install openFoam v1612+ from openfoamwiki

but nothing has improved

what should I do?

Please tell me the solution.

[unners]

Thanks for the help. It's definitely a 64 bit ubuntu version. I can get the GUI window to load up as per your picture below. The errors only occur when trying to run any of the tutorials.

Cheers

Hi unners,

The errors only occur when trying to run any of the tutorials.

This first version of the GUI has been created to just work with some specific parameters, in order to reduce the possible choices of the new users.

Therefore, you need to modify the decomposeParDict and change "coeffs" by "hierarchicalCoeffs"

Then, the GUI should work fine and load your case.

Best Regards,
IHFOAM Team.

Hi,


Just wanted to say that I was having the same issue as unners and changing "coeffs" by "hierarchicalCoeffs" worked!
Thank you for your help.

Hi Tomás,

We are happy to have some feedback from the community and see that the GUI is being used.

We have been working in a newer version of the GUI, that it will be released very soon: new features, new design to do it even more friendly and robust, and of course, to be adapted to the newer features of the code.

Please, let us know if you have any comments, thoughts or suggestions that you would like to see in the upcoming release.

Best,
IHFOAM Team.

Dear IHFOAM team member,


Thank you for the quick and helpful responses. It's great to know you are working on an even better GUI, I'm looking forwards to using it! I will make suggestions for it if I find any problems with the current GUI.

I am just starting with OpenFOAM and the IHFOAM-GUI, but I am happy to share some of my difficulties so far: (I'm running Ubuntu 18.10 and OpenFOAM v1812 installed from source)

1- I had difficulties finding ParaView's location. Some things aren't so obvious for beginners as they are for more experienced users. Maybe make the GUI find it automatically or give some indications of where it might be.


When doing the waveExampleStokesV tutorial:


2- In the blockMeshDict change "scale" to "converToMeters".



3- Running blockMesh gave an error related to the "......./libstdc++.so.6: version 'GLIBCXX_3.4.22' not found. Found a solution online: delete "libstdc++.so.6" from folder IHFOAM_GUI/dist/main. From what the forum explained, it then uses Ubuntu's library (and not IHFOAM's). Anyway, it worked.

4- That detail you mentioned earlier of changing "coeffs" to "hierarchicalCoeffs" in the decomposeParDict.

5- When clicking "setFields" I got an error. Go to Numerical Setup, fvSchemes, fluxRequired, change default to "yes" and check the alpha.water box. I realised that if you change default to "no" and don't check any boxes, it also works. Not sure of which to chose. Can you give some feedback on this please?


6- Could you please share the final waveExampleStokesV tutorial folder? It might be good to compare with our files when we encounter errors.



Kind regards,
Tomás

Dear IHFOAM Team,


I am working on studying the overtopping flow over a breakwater. I am using the surfaceFieldValue function, defining a faceZone on top of the breakwater and measuring the flow through it. I added this code to the controlDict:

    overtopping
    {
        type            surfaceFieldValue;
        libs            ("libfieldFunctionObjects.so");
        
        log            true;
        writeControl        timeStep;
        writeFields         true;

        surfaceFormat        none;
        regionType          faceZone;
        name            galgamento;

        operation        sum;
        weightField        alpha.water;
        fields            (phi);
     }

and this code to the topoSetDict:

 actions
(
    {
        name    g;
        type    faceSet;
        action  new;
        source  boxToFace;
        sourceInfo
        {
            box (14.410 0 .75)(14.456 0.04 1);
        }
    }

    {
        name    galgamento;
        type    faceZoneSet;
        action  new;
        source  setToFaceZone;
        sourceInfo
        {
            faceSet g;
        }
    }

  );

For a solitary wave, I get a csv file with a time-series of values. Dividing those values by the width of the faceZone, I get the following graph:




I am not sure of what these values represent, but I think I have the flow in m3/s/m right? Or should I integrate to get it? (I am working at a scale of 1:50 just as reference).

Thank you very much for your help!


Best regards,
Tomas

Hi Tomas

I'm still battling away trying to get the GUI to work. Can I ask you a couple of questions? Are you running Ubuntu within Windows 10 (WSL)?

Where did you find the Paraview installation in the end? I've installed the windows build paraview, but can't seem to point the GUI to the bin folder in the program files.

Running blockMesh for me gives this error which I can't seem to get past:

/bin/sh: 1: eval: Syntax error: "(" unexpected

Thanks in advance for any help!

Cheers

Dave

We have never tried this way, and I not sure if it will work; we always work in ubuntu, so the GUI was created to look for an linux executable.

This is a normal OpenFOAM error, please compare your blockMesh dictionary with one of the tutorials, It seems that there is a bracket missing somewhere.

Please, let us know any new feature or improvement that you would like to have in the newer version. It will be released after summer, and we have put all our effort in creating a very robust tool with a complete new design.

Hello Dave,


Sorry for the late reply, I haven't been using OpenFOAM recently and so I haven't come to the forum. The IHFOAM Team has already replied to your questions, but just for your information I am running the IHFOAM-GUI in Ubuntu. About the second error, I don't have any more clues than the IHFOAM Team member.
The Paraview location in Ubuntu is /home/username/OpenFOAM/ThirdParty-v1812/platforms/linux64Gcc/ParaView-5.6.0/bin/paraview

Let me know if I can be of any help!


Kind regards,
Tomás

Dear IHFOAM Team,


I have been struggling with how to plot the time series of the water free surface, and using it to validate the results against experimental tests.
I created line probes using the GUI, and the alpha.water values are stored in the postProcessing/line folder, separated by time step. Inside, there is a file for each line probe showing the value of alpha.water from 0 to 1 on 0.01 steps. Here is an example for one probe for one time step:

0     1
0.01     1

Thank you very much for your help.

Hi,
I'm a student who is currently doing my dissertation on numerical simulation. And I found IHFoam GUI very interesting and helpful for my dissertation. I was getting familiarized with IHFoam GUI, and going through the tutorial.
Tutorial no 4, regular wave interaction with Rubble-mound breakwater, after importing the crownWall, it is not visible in my Domain Viser and also after running the setFields, the whole rubblemound breakwater is missing. The visible part is only water and the blockMesh output.
I'm kind of running out of time hence would appreciate it if anyone can assist me in solving this issue.
Thank you

Regards,
Asra
