Contribution
It introduces a Python-based tool for automated, iterative control of the CHEASE equilibrium solver, facilitating better alignment with experimental plasma data.
Findings
Enables iterative convergence to experimental plasma current
Automates equilibrium calculations with Python scripting
Supports validation of MHD equilibrium preservation
Abstract
CheasePy is code written in Python to run the CHEASE (Cubic Hermite Element Axisymmetric Static Equilibrium) code, which solves the Grad-Shafranov equation for toroidal MHD equilibria using pressure and current profiles and fixed plasma boundaries that is defined by a set of experimental data points (R,Z). The CheasePy code allows an iterative running of the CHEASE code either to check the preservation of MHD equilibria or converging to an experimentally defined total toroidal plasma current by modifying any input quantity.
