INERT VS Isothermal VS Adiabatic boudariy conditions

[LordNarcisse]

Hi,

I am conducting a comparative study between several boundary conditions for surfaces.
In FDS, the INERT condition is described as a surface with a temperature fixed at TMPA (ambient temperature).

What differences in heat transfer could there be with an isothermal case described as follows:

&SURF ID='ISOTHERMAL', TMP_FRONT=20.0 /
&OBST XB = Xmin, Xmax, Ymin, Ymax, Zmin, Zmax, SURF_ID='ISOTHERMAL' /

Finally, does FDS calculate anything extra in the INERT case, or is setting an INERT condition equivalent to using an isothermal condition?

Thanks,

Alexandre

TMP_FRONT=20 is equivalent to INERT with TMPA=20.

Thanks for your answer.
