这个软件包提供的例程可以扩展器读取并绘制网格，现场并指出文件。 Extender是一个环形等离子体计算上的代码从一个平衡代码（如VMEC或馅饼）电网的磁场。该扩展器的代码是由迈克尔Drevlak在等离子物理研究所。-This package provides routines to read and plot the EXTENDER mesh, field and points files. EXTENDER is a toroidal plasma code which calculates the magnetic field on a grid from an equilibrium code (such as VMEC or PIES). The EXTENDER code is maintained by Michael Drevlak at the Institute for Plasma Physics.
