AB - <p style="text-align: justify;">Flux coordinates and field-line coordinates are ubiquitous in magnetically
confined plasma research. Most of these coordinates are essentially non-orthogonal
curvilinear coordinates, in which the differential operators are rather complicated.
This article reports an automatic tool, <em>OpGen</em>, for generating a finite difference coefficient matrix for field solvers by using a computer symbolic computation system.
This tool is suitable for, but is not limited to, code development for toroidally confined
plasmas.</p>
