Hi,

The usage of externalWallHeatFluxTemperature is the following:
<patchName>
{
type externalWallHeatFluxTemperature;
kappa fluidThermo;
q uniform 1000;
Ta uniform 300.0;
h uniform 10.0;
thicknessLayers (0.1 0.2 0.3 0.4);
kappaLayers (1 2 3 4);
value uniform 300.0;
kappaName none;
Qr none;
relaxation 1;
}
\endverbatim

Note:
- Only supply \c h and \c Ta, or \c q in the dictionary (see above)
- \c kappa and \c kappaName are inherited from temperatureCoupledBase.
------------
But, I got an error of "kappaMethod is undefined. I need to change to
kappaMethod fluidThermo;

Is this a typo error?

Seems that the instructions are not updated, but the code is not consistant either. there is no "kappaMethod" here: https://github.com/OpenFOAM/OpenFOAM...hScalarField.C

the following sintax works for a fixed heat transfer heated wall:

   "fluid_to_.*"  
   { 
      type             externalWallHeatFluxTemperature;
      kappa            fluidThermo; 
      kappaMethod      fluidThermo;
      q                uniform 264; 
      value            uniform 293.7;
   }

Quick answer: Unfortunately that's one example of having the same documentation in several places. When one if fixed, all others may or may not be updated.

If you follow the link online for the "temperatureCoupledBase" class, you'll find the description here: http://cpp.openfoam.org/v4/a02649.html#details

The change that occurred was reported in the following commit: https://github.com/OpenFOAM/OpenFOAM...e92188c3953b8e

temperatureCoupledBase: Rationalized the selection of the method for obtaining the thermal conductivity

kappa -> kappaMethod
kappaName -> kappa

I'll submit a patch for 4.x and dev in a few minutes and update this post accordingly.

Furthermore, next time you pick-up this kind of typo, please do report it at http://bugs.openfoam.org
