Version: 5.0

The new version - CORHEL V5.0 differs from the previous versions principally in the inclusion of a version of MAS supporting a full thermodynamic energy equation, as well as the polytropic implementation in the previous version.

CORHEL is a software package that: (1) obtains and processes photospheric magnetograms; (2) runs the coronal model (either MAS or WSA); (3) processes the results to generate boundary conditions for the heliospheric code; and (4) runs the heliospheric model (either MAS or ENLIL).
