Hi all,

I have included the following in my controlDict file
type sets;
libs ("");
enabled true;
verbose true;
interpolationScheme cellPoint;
outputControl timeStep;
outputInterval 1;
setFormat raw;
type lineUniform;
axis z;
start (-0.5 0.5 0);
end (0.5 0.5 0);
nPoints 500;
type lineUniform;
axis z;
start (-0.5 -0.5 0);
end (0.5 -0.5 0);
nPoints 500;
type lineUniform;
axis z;
start (0.5 -0.5 0);
end (0.5 0.5 0);
nPoints 500;
I could write the pressure data at the specified location. But it generates
a new folder for every time step and writes the data inside that folder.
Can someone help me how to append the data in one file.

S Jawahar.
