 The procedure solving coupled TH transfers with phase change was developed based on the core procedure TRANGEOL solving time step Eulerian transport (diffusive-dispersive & advective transport). TRANGEOL provides a variety of options: a VF (Le Potier 2004, 2005, 2010) or a MHFE (Mosé et al. 1994; Dabbene et al. 1998) numerical scheme, theta-methods (from implicit to explicit) for diffusion and advection, as well as various options for system matrix inversion and conditioning (www-cast3m.cea.fr). It was largely tested for nuclear waste storage applications showing the practical pros and cons of most of these options and approaches.  The procedure solving coupled TH transfers with phase change was developed based on the core procedure TRANGEOL solving time step Eulerian transport (diffusive-dispersive & advective transport).

-To resolve the TH benchmark cases the TRANGEOL procedure was used with the implementation of new development, 1°) adding the phase change term and 2°) solving the set of non-linear coupled equations by means of a Picard iteration scheme. So some points are detailed below. +To resolve the TH benchmark cases the TRANGEOL procedure was used with the implementation of new development, 1°) adding the phase change term and 2°) solving the set of non-linear coupled equations by means of a Picard iteration scheme. Some points are detailed below.
