breakwater, overtopping calculation

cfxmar · March 30, 2011, 09:31

I´m simulating the impact of waves on a breakwater.
I need to calculate the overtopping, that is, the water volume falling over the breakwater. I have tried with expressions like:

Water at 25 C. Volume@region and it doesn´t work.

Could kindly anyone tell me how to calcule it?

Look at the CFX Reference manual for how to use these functions. Volume gives the volume of a region. You want to integrate the volume fraction over the domain to get the amount of water. Try volumeInt(Water at 25C.Volume Fraction)@Region or something like it.
