Hi all, I had an issue when using OFv7 to simulation a ship in wave condition.

As far as I know, OpenFOAM has included its own wave generation tool since OFv5.

To start with, I copied the DTCHullWave tutorial case into my own directory then I replaced the STL file and then did my own blockMesh, refineMesh and snappyHexMesh etc. Then I did renumberMesh, the error reported:

--> FOAM FATAL IO ERROR:
Essential entry 'value' missing

file: /home/OpenFOAM/OpenFOAM-7/run/KCSDRIFTINWAVE/0/U.boundaryField.inlet from line 31 to line 31.

Then I had to add value in alpha.water and U files in 0 folder (value $internalField; in both inlet BCs in both files)

Then setWaves and decomposePar ran smoothly without any error.

Finally, running interFoam, error reads: Unknown patchField type waveVelocity for patch type patch; (/0/U.boundaryField.inlet)

I think the same error will reported in 0/alpha.water.inlet as well for Unknown patchField type waveAlpha for patch type patch;

Please let me know if you have any hint to resolve this issue! Many thanks and Btw I am using OF version 7 and the patches of waveAlpha and waveVelocity should have been included in OFv7, and I can run DTCHullWave tutorial case without any error!

Btw, I am not sure whether it is worth installing a third party wave generation tool eg. wave2Foam in OpenFOAM v7?

Any help will be appreciated!
