Hello everybody

GGI weighted interpolation seems to be used for fluxes on master and shadow patches on an interface but I would like instead to apply it to an electric field displaying a discontinuity at the interface. All I'm asking is where this function resides in the foam extend code so that I can call it using the electric field as parameter.

Any response would be greatly appreciated.

Best,
Marc

Well, after some detective work using Linux commands grep and find, I discovered that the Sutherland-Hodgman algorithm resides in file SutherlandHodgman.C in folder

./foam-extend-4.0/src/foam/algorithms/polygon/clipping/


and that file GGIInterpolation.C resides in folder

/.foam-extend-4.0/src/foam/interpolations/GGIInterpolation/

that same file has 4 includes after the end of namespace Foam:

# include "GGIInterpolationPolygonIntersection.C"
# include "GGIInterpolationQuickRejectTests.C"
# include "GGIInterpolationWeights.C"
# include "GGIInterpolate.C"

also residing in the same folder

In GGIInterpolationPolygonIntersection.C , is a call to the Sutherland-Hodgman algorithm


Hopefully, I should be very close to plugging in the desired electric field. Perhaps, somebody can now shed me some light in this quest


Thanks,

Marc
