Hi Foamers,


I would like to visualize, in Paraview, values which are written within field directories in each time directory but are not fields. These values are calculated during the calculation of the fields. The following is an example:


Code:
/*--------------------------------*- C++ -*----------------------------------*\

// ************************************************************************* //
Now lets say, that I want to visualize the regimeType, not the alphat.liquid which is the field. I do not want to create a new field as this value is provided only once debug switch is on.



Apparently, I can code OF utility or python script to make a dummy field directory called regimeTypes in each time directory. I just wonder whether there is some standardize procedure to it.



Thanks,
Robin
