I have a pipe with heat flux outside, I have a line of point inside the pipe with a fluid, I should have the temperature the pressure and de Nusselt Number, but for temperature and pressure I have normal result but in the case of Nusselt Number my values are always 0. anyone know what is happening? we can see the pictures.

For the Nusselt number field function you need to specify reference length, temperature and thermal conductivity.

I used this values in the referent and the position is ok, because I have normal pressure and temperate in my point line

Ok, are you using the pipe surface as input to the line plot?

I was not using the pipe surface as input, I was using the fluid!


thanks!!!!
