irwin is on a distinguished road
i am tracking interface while using interFoam solver using code placed in the controlDict
functions
{
elevation
{
type surfaces;
functionObjectLibs
(
"libsampling.so"
);
outputControl outputTime;
outputInterval 1;
surfaceFormat vtk;
interpolationScheme cellPoint;
fields
(
alpha.oil
);
surfaces
(
topFreeSurface
{
type isoSurface;
isoField alpha.oil;
isoValue 0.5;
interpolate true;

log true;
interpolationScheme cellPoint;
}
);
}

This generate VTK file at every time step , Then I have to read that VTK file using paraFoam at each time step to extract the surface which is quite a tedious task . I am looking for any convenient method by which I can directly extract the surface in one go.

Thanks,
Irwin
