Hi All,

I am not able to see the output of the debugSwitch for the nutWallFunction after it is appended to my controlDict file for the damBreak tutorial on OpenFoam 2.2.0 using a desktop as:

application interFoam;
startFrom latestTime;
startTime 0;
stopAt endTime;
endTime 1;
deltaT 0.001;
writeControl adjustableRunTime;
writeInterval 0.05;
purgeWrite 0;
writeFormat ascii;
writePrecision 6;
writeCompression uncompressed;
timeFormat general;
timePrecision 6;
runTimeModifiable yes;
adjustTimeStep on;
maxCo 0.2;
maxAlphaCo 0.2;
maxDeltaT 1;

DebugSwitches
{
nutWallFunction 1;
}


The nut file in the 0 directory uses the wall function on the wall such as:

lowerWall
{
type nutkWallFunction;
value uniform 0;
}


so I assume there should be some debug info but while the output shows the user supplied change to the debugSwitch, I don't see any output for the nutWallFunction.

Create time

Overriding DebugSwitches according to controlDict
nutWallFunction 1;


Create mesh for time = 0

What am I missing? Are the results elsewhere? Is this the wrong debugSwitch (I've tried several and don't see any difference in the output log)?

Related to this issue is when I run the same case (OF 2.1.1) on a cluster, not only do I not see any output of the Wall Funciton in the log file, but the statement acknowledging my debug switch "Overriding DebugSwitches according to controlDict
nutWallFunction 1;"

is also absent from the output log. Any ideas on how to solve this (maybe a permissions issue?)?
