CREATE-FXB, a Fixed Boundary Code Based on Finite Element Methods for the Solution of the Grad–Shafranov Equation and Optimization of Equilibrium Currents

Year: 2025

Type: article

Abstract: CREATE-FXB is a Finite Element Method solver specifically developed to address the fixed-boundary problem, namely the determination of the Magnetohydrodynamic equilibrium of an axisymmetric plasma confined within a toroidal nuclear fusion device. Although several solvers are already available and widely used, CREATE-FXB repre-sents a valuable alternative with further improvements, as it introduces a set of dis-tinctive capabilities that extend its applicability and accuracy in modelling this class of problems. Its key features include the design of plasma scenarios in tokamaks, the derivation of linearized plasma response with high accuracy, the treatment of a wide class of current density profiles including non-smooth distributions, and an improved capability of interfacing with other existing codes.
