ComPASS aims at being an open, evolutive platform for hydrothermal modeling. It implements state of the art numerical scheme to discretize multiphase Darcean flows on generic unstructured meshes. It is currently developed in the framework of the charms ANR project which has a specific focus on the integration of geological models and dynamic models.

Our main goals are:

• to achieve an intuitive high-level API with simple scripts and a DSL-like approach based on Python,
• target the specification of the physics at the level of the python script without loss of efficiency to be able to develop and reuse easily different physics.

The collaborative development is made through the INRIA gitlab platform and the documentation is served here.
