CFD Online Discussion Forums - available objects for fieldAverage

Dear all,

I'm working on lagrangian particles.
In this context, I'm using the variable kinematicCloudTheta, which is computing in KimenaticCloudI.H. And I've modified the code, to create the file kinematicCloudTheta at each output time. The problem is that I also wish to compute the time average of this variable with the function fieldAverage, and I get then the following error :

in file /students/rm_11_12/specklin/OpenFOAM/OpenFOAM-2.1.x/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 131.

FOAM aborting

Does somebody has an idea about how to get rid of this error?
My variable is only computed in the source files, and is not created in the createFields of the solver. (and it should be like that)

Best,

Mat
