The numerical simulation of an air bubble bursting at a free surface was made in a potential flow of a viscous fluid assumption, through the Boundary Element Method. The evaluation of the numerical code precision was allowed trough a global mechanical energy balance, expressed only in surface integrals terms. The bubble cavity collapse behaviour, finalised by the jet formation and its successive break up, depends on the regridding performed during the whole computation.
