Outputting data
 

Hi, I am performing a 3D transient calculation. Is it possible to output variable values on a plane (say at the grid nodes that lie in that plane), at every time step?

I see that it is possible to plot variables and output them to PPM files, but I couldn't find a place to output the raw data itself. I am inexperienced (2 weeks) in writing UDFs, so instructive examples will help.
