L’équation (5.5 a) correspond à la condition de Neumann appliquée à l’interface tant que le
mécanisme de l’ablation n’a pas été initié Dès lors que la température de fusion est atteinte,
l’estimation de v r locale correspondante à la vitesse de régression de l’interface fluide/solide
est effectuée par l’intermédiaire du bilan énergétique ; le flux de chaleur est divisé en un flux
de conduction pénétrant à l’intérieur de la matière solide et de l’énergie contenue dans la
matière ainsi ablatée. Dès que le mécanisme d’ablation a eu lieu, l’interface  ( t ) est en
mouvement avec la vitesse v r et l’interface du solide doit être estimée et située dans le temps.
Le suivi de l’interface est assuré par la technique des frontières immergées et ceci permet donc
de suivre l’interface et ses modifications sur l’ensemble de la simulation.

The equation (5.5 a) corresponds to the Neumann condition applied to the interface as long as themechanism of ablation was not initiated as the melting temperature is reached,the corresponding local r v estimate at the speed of the fluid/solid interface regression is performed through the energy balance; the heat flow is divided into a streamconduction penetrating inside the solid matter and energy contained in theso ablatee material. As soon as the ablation mechanism took place, the interface  (t) ismoving with speed v r and the interface of the solid must be estimated and located in time.The interface is tracked by the technique of submerged borders and allows thereforefollow the interface and its changes throughout the simulation.

Equation (5.5 a) is the Neumann condition applied to the interface as the
removal mechanism was not initiated Since the melting temperature is reached,
the corresponding local estimate of vr the regression rate of the fluid / solid interface
is performed via the energy balance; the heat flow is divided into a flow
conduction into the interior of the solid matter and the energy contained in the
thus ablated material. Once the ablation mechanism has occurred, the interface  (t) is in
movement with the speed vr and the interface of the solid must be estimated and based in time.
The monitoring of the interface is provided by the Technical submerged boundaries and this therefore makes it possible
to follow the interface and changes over the entire simulation.

equation (5) corresponds to the neumann condition applied to the interface so that the ablation mechanism was initiated as soon as the melting temperature is reached, the estimation of the local velocity of the fluid / solid interface, regression is carried out through the the energy balance and the heat flux is divided into a flow.when the conduction inside the solid, and the energy in the field, and ablatée. as soon as the mechanism of removal has taken place, the interface  (t) is moving with speed v and r, and the interface of the solid should be estimated within the monitoring time. the interface is provided by the technique of underwater and this allows border.monitor interface and its variations throughout the simulation.
