Thermal boundary implication (constant heat flux)

I found this quota in a paper, why implementation of constant heat flux is difficult?
"For the thermal boundary condition, the temperature distribution along the pipe wall was specified, based on the data. Although a constant heat flux was applied as the thermal
boundary condition in the experiment, with the present DNS technique it is didifficult to treat a constant wall heat flux condition for spatially developing flow problems"
Thanks for your time

From this statement is not clear .... as DNS is referred as, the number of grid point in the thermal BL have to be sufficient to impose a Neuman BC.
