// XD puissance_thermique source_base puissance_thermique NO_BRACE Class to define a source term corresponding to a
// XD_CONT volume power release in the energy equation.
// XD attr ch field_base ch REQ Thermal power field type. To impose a volume power on a domain sub-area, the
// XD_CONT Champ_Uniforme_Morceaux (partly_uniform_field) type must be used. NL2 Warning : The volume thermal power is
// XD_CONT expressed in W.m-3 in 3D (in W.m-2 in 2D). It is a power per volume unit (in a porous media, it is a power
// XD_CONT per fluid volume unit).
 
/*! @brief Reads the thermal power term from an input stream and an equation, possibly using the discretisation to type la_puissance.
 *
 *     Reads only the prescribed field representing la_puissance.
 *
 * @param is An input stream.
 * @param eqn The equation owning this source term.
