hi,
I'm trying to identify the amount of water passing a plane. to achieve this, I add a functionObject in my controlDict. the function added is shown below. The case is a simpler version of damBreak, which is some water dropping from the air(see attachment). Code:
functions { flux { functionObjectLibs ("libfieldFunctionObjects.so"); type surfaceFieldValue; enabled true; writeControl outputTime; writeInterval 1; writeFields true; name myName; surfaceFormat none; // regionType: patch/faceZone/sampledSurface regionType sampledSurface; sampledSurfaceDict { type plane; planeType pointAndNormal; pointAndNormalDict { point (0.1 0 25); normal (0 0 1); }; interpolate false; } // Operation: areaAverage/sum/weightedAverage/... operation areaNormalIntegrate; fields ( U ); } } Code:
interFoam -postProcess Code:
# Region type : sampledSurface myName # Faces : 178 # Area : 8.900000e+00 # Time areaNormalIntegrate(U) 0.05 (1.601638e+00 0.000000e+00 0.000000e+00) Code:
