Welcome to the HEAT project

Overview

Latest-generation atmospheric models carry the promise of addressing scientific issues that remain out of reach with current operational models. Putting them to work to answer scientific questions nevertheless requires significant effort and collaboration between experts of the numerics, computing, and scientific use of such models. HEAT sets up such a collaboration in order to address extreme atmospheric modelling applications and remaining numerical and computational challenges. Our specific objectives in terms of atmospheric sciences are to pioneer numerical modelling of the general atmospheric circulation of gaseous giant planets and to achieve milestones towards millenial-scale Earth system simulations relevant for palaeoclimatology. In terms of numerical and computational challenges, our objectives are to address the higher-order extension of highly scalable numerical methods for transport and dynamics, and bottlenecks for non-hydrostatic modelling, especially elliptic problems.

Les modèles atmosphériques de dernière génération laissent entrevoir des possibilités d'investigation scientifique hors de portée des modèles opérationnels actuels. Mais leur utilisation effective pour répondre à des questions scientifiques requiert un effort considérable et une collaboration entre experts des applications et des aspects numériques et informatiques de ces modèles. HEAT met en place une telle collaboration pour aborder des applications extrêmes de la modélisation atmosphérique ainsi que des questions numériques et informatiques. Spécifiquement, nos objectifs en termes d'applications sont la circulation générale des l'atmosphère des géantes gazeuses et la modélisation du système Terre à l'échelle de milliers d'années, objectif de long terme vers lequel des jalons seront posés. En termes de questions numériques, HEAT se concentrera sur la montée en ordre de méthodes efficaces et scalables pour le transport et la dynamique, ainsi que sur des obstacles à l'efficacité des modèles non-hydrostatiques, notamment la résolution de problèmes elliptiques.

The Themis FEM framework

Themis is a PETSc-based software framework for parallel, high-performance (*) , automated (*) discretization of variational forms (and solution of systems of equations involving them) through mimetic, tensor-product Galerkin methods. It is intended to enable a rapid cycle of prototyping and experimentation, accelerating both the development of new numerical methods and scientific models that incorporate them.
