Type of convection heat transfer boundary?
 
what is type of convection boundary?
it is not fixedGradient because:
(T_s - T_inf) h = k dT/dx => T_s= (k/h)dT/dx + T_inf

So we can't use fixedGradient because of T_s (Surface temperature) is not a fixed value.:confused: it is needed for laplacianFoam and temperature field of a solid channel.
