A fluid domain may carry thermal settings: the initial temperature, gravity and the fluid's expansion coefficient for buoyancy, and a thermal condition (adiabatic, held temperature, heat flux) on each box face and on named obstacle faces, adiabatic unless told otherwise. The material then needs an isotropic conductivity and a specific heat. Boundaries are set one at a time like the flow ones. Part of #157.
