Hi Niels,

In order to learn how to calculate overtopping rate, I read the relevant file overtopping.C. And in the member function " void Foam:vertopping::computeAndWrite ()", the momentum flux is calculated as follows,

f[facei]=rho1_*q[facei]*Foam::mag( q[facei]/magSf[facei] );

And I wonder if the term magSf[facei] should be replaced by magSf[faceI]??

Hallo Xiantao,

Thank you for the bug report. The bug has been fixed and submitted to the svn.

Have a nice day,

Hi Niels,

After reading the source file overtopping.C. My idea of how to use overtopping as a functionObject is as follows,

Adding the following sentences in the controlDict

overtoppingAnyName
{
type overtopping;
functionObjectLibs ("libwaves2Foam.so");
outputControl timeStep;
outputInterval 1;
}

And one thing to mention is that the name of the faceZone (used for extracting the overtopping rate) should be "overtopping".

Is it right for calculating overtopping rate??

Hi Xiantao,

Yes it looks correct, though you might need another library (the sampling one in waves2Foam).

Note that you can have multiple overtopping zones, and long as the faceZone starts with 'overtopping', e.g. overtopping01, overtopping02, etc.

Kind regards

Niels
