PyMT

Python Modeling Toolkit (pymt)

pymt is an Open Source Python package that provides the tools needed to run and couple models that expose the Basic Model Interface (BMI).

pymt contains:

• Tools necessary for coupling models of disparate time and space scales (including grid mappers)
• Time-steppers that coordinate the sequencing of coupled models
• Exchange of data between BMI-enabled models
• Wrappers that automatically load BMI-enabled models into the PyMT framework
• Utilities that support open-source interfaces (UGRID, SGRID, CSDMS Standard Names, etc.)
• A collection of community-submitted models, written in a variety of programming languages, from a variety of process domains -- but all usable from within the Python programming language
• A plug-in framework for adding additional BMI-enabled models to the framework

pymt is an element of the CSDMS Workbench, an integrated system of software tools, technologies, and standards for building and coupling models.
