Hello, nOne way of doing this could be to make use of DEFINE_ON_DEMAND UDF.nIf you know the co-ordinates of the center of this cell, then you can check it inside the UDF when looped over all the cells.nIf it matches (or if it is very close if exact match is not possible), then you could use the macro C_VOLUME(c,t) to calculate the volume.nwhere c is the cell id and t the corresponding thread of that particular fluid cell.nRegards,nSuryan
