convective heat flux magnitude

Hi ,

I'm computing heat transfer from a rotating hot sphere in a fluid medium. The flow is creeping type.

I have issues related to the various COMSOL options for convective, conductive and total heat transfer. Is there any documentation about how COMSOL computes these quantities. For instance the "convective heat flux" gives a zero value while "convective heat flux magnitude" gives close to 20 kw. In principle the correct value should be zero. I even looked for this in the documentation but failed to find any. I would appreciate if someone can share some light on this.
