During a thermic evolution, i met problems in the boundary of convection boundary conditions which have different
transfer coefficient. There spacial oscillations of the temperature field. This phenomenom doesn't appear of the steady situation by RESO.
To diagonalize the capacity matrix in PASAPAS can stabilize the problem. It is also possible to increazse relaxations coefficients :
RELAXATION_THETA
RELAXATION_DUPONT
SOUS_RELAXATION
