Dear Foamers,

I'm quite new to using irregular waves, there seemed to be some problems(elevation-related problems) with my focusing waves

wondered whats the problem

blockMesh as follows

{
version 2.0;
format ascii;
class dictionary;
object blockMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

convertToMeters 1;

);

did used this same meshing for my combinedWaves simulation (10 waves, with wave heights ranging from 1.2cm to 3.7cm) and was fine

My control dict as follow

application interFoam;

startFrom latestTime;

startTime 0;

stopAt endTime;

endTime 9;

deltaT 0.0004;

writeControl adjustableRunTime;

writeInterval 0.25;

purgeWrite 0;

writeFormat ascii;

writeCompression uncompressed;

timeFormat general;

timePrecision 6;

runTimeModifiable yes;

adjustTimeStep yes;

maxCo 0.2;

maxAlphaCo 0.3;

maxDeltaT 1;

My JONSWAP wave properties as below

seaLevel 0.00;

// A list of the relaxation zones in the simulation. The parameters are given
// in <name>Coeffs below.
relaxationNames (inlet outlet);

initializationName outlet;

inletCoeffs
{

gamma 3.3;

frequencyAxis
{
writeSpectrum true; // false = default value

discretisation equidistantFrequencyAxis; // cosineStretchedFrequencyAxis;

lowerFrequencyCutoff 0.1; // Not required. Default: 1/3fp
upperFrequencyCutoff 2; // Not required. Default: 3fp
}







relaxationZone
{
relaxationScheme Spatial;
relaxationShape Rectangular;
beachType Empty;
relaxType INLET;
startX (0 0.0 -1);
endX (4 0.0 1);
orientation (1.0 0.0 0.0);
}
};





outletCoeffs
{
waveType potentialCurrent;
U (0 0 0);
Tsoft 0;

relaxationZone
{
relaxationScheme Spatial;
relaxationShape Rectangular;
beachType Empty;
relaxType OUTLET;
startX (11 0.0 -1);
endX (16 0.0 1);
orientation (1.0 0.0 0.0);
}
};

screenshot of my surface elevation at point of focusing, seems like no waves are produced, well, i did see some microwaves producing in paraFoam,
Screenshot from 2017-03-13 17-21-59.png

any inputs would be greatly appreicated thanks all

Hi Chia,

I suppose it is because your focus time is larger than your end time. You could also verify that the expected amplitudes and phases are written to waveProperties.

Kind regards

Thanks Niels, for the reply

I tried re-running a regular wave simulation, and found that no waves were generated. I admit i think I may had compile wavefoam wrongly on my new working environment.
I'm actually working on a new environment and I tried compiling wavefoam by using of301

I tried to copy my simulations that Ive successfully used in my old workplace using of301, and my current work station doesnt recognize the inlet boundary type of alpha1.org (doesnt recognize waveAlpha) ,

boundaryField
{
inlet
{
type waveAlpha;
refValue uniform 0;
refGrad uniform 0;
valueFraction uniform 1;
value uniform 0;
}

Hence, i tried changing it to fixedValue and no waves were made, thats prolly the case im facing,

I went back to execute ./Allwmake , this is what I got

COMPILATION DONE
=====================================

it seems that in the waveFoam.C , there are alot of commands or items 'not declared' and i think that could be the root of the problem, any insights on how to proceed further?
thanks for your kind patience

Hi,

You must have created the solver yourself, as 3.0.1 is not supported with solvers. You are likely missing files, but I cannot help in narrowing it down.

Kind regards

Niels
