Adapting block method to solve moist air flow model

Coupled problems describing global thermal behaviour of buildings are diffi cult to solve. We are interested here in the numerical resolution of algebr aic non-linear systems corresponding to the steady-state behaviour. After a short description of the physical problem, main ideas of block methods are presented. Then splitting of the analysed model is discussed and the perfo rmance of block methods is evaluated. Finally, a robust hybrid block strate gy, well adapted to moist airflow modelling is elaborated. (C) 2000 IMACS. Published by Elsevier Science B.V. All rights reserved.
