Default Probe function not recording data

I am trying to use the probe function in controlDict to record the solution from my solver at different points in a duct. However, when I run the solver, only the first time step is found in the post processing folder which is no good because I want to look at the flow behaviour over time. I have used probesDict as a post processing tool but I found that my data are massive and I don't really need the solutions to all other locations. Can anyone please help point me in the right direction?

Here is my controlDict file:

application mhdsolver;

startFrom latestTime;

startTime 0;

stopAt endTime;

endTime 3.5;

deltaT 0.0001;

writeControl timeStep;

writeInterval 6;

purgeWrite 0;

writeFormat ascii;

writePrecision 6;

writeCompression uncompressed;

timeFormat general;

timePrecision 6;

graphFormat raw;

runTimeModifiable yes;

adjustTimeStep yes;

type probes;

outputControl timeStep;
outputInterval 1;


(8 0.0 0.0)

well - the probe writes the data to a file which is called after the time it starts writing, therefore in that file you have values for each time in a line. In the first line you have names of variables in columns.

In your case it will look like:

time Ux Uy Uz T p PotE

for more points the set of columns would repeat to the right.

good luck
