Modeling the wave generation by an oscillating body I need to set a boundary condition which prevents wave reflection by absorbing its energy. For short wavelengths, stretching grids in the advancing direction will work but for long waves it is needed to insert a porous zone in the vicinity of outlets or to impose a dissipation function so that waves in flow boundaries cut down. Inserting the porous media will enlarge domain and thus more computational efforts will be required. For imposing a dissipation function as a numerical beach I read the presentation of Paterson for OpenFoam: http://powerlab.fsb.hr/ped/kturbo/op...nNuTTS2009.pdf - slides#16, 17. I really get confused how should I this dissipation function and more important how can I impose this function to the whole domain?
Is initialization with such a function gonna help?
I m looking for your helps please.
waves/numerical beach in CFX
I want to model waves in CFX
I came across a numerical beach simulation. I would like to know if there are any CFX tutorial files available for doing this.
