Hello, Niels,

I have some confusions about the term 'initializationName' suggested in waveProperties.input.
this term appears twice in openfoamWiki
1. The entry initializationName in waveProperties defines which sub-dictionary is used for initialising the wave field.
2. //Used by setWaveField and it is the sub-dictionary,
// which defines which wave theory to be used for initialization

what confuses me is why the term 'initializationName' is set to 'outlet' in each 'waveProperties.input' file rather than 'inlet'. actually, after I change it to 'inlet'
error comes out:

FOAM Warning :
From function setWaveField::setWaveField( const fvMesh& mesh, volVectorField& U, volScalarField& alpha, volScalarField& p)
in file preProcessing/setWaveField/setWaveField.C at line 77

The specified value of Tsoft is non-zero in the waveType: `stokesFirst'
specified in the sub-dictionary waveProperties::inletCoeffs

Consequently, the initialised `wave field' is set to a horizontal free surface with zero velocity.

thanks for your attention.

Good morning,

@Yalong: The program does the right thing. The choice of using the outlet for initialisation is merely random. When Tsoft > 0 it does not matter. If is only if you want a non-flat initial field that you have to think about the zone to use and the magnitude of Tsoft.

Kind regards,

Niels
