ONETWO 是一种一维半、与时间相关的计算机代码，用于模拟托卡马克中的等离子体传输。圆形和非圆形横截面等离子体（包括双合态）都可以与场整形线圈中的电流一起进行建模。可以同时考虑电子、几种离子和两种中性物质。电子和离子被视为流体，而中性粒子被动力学处理。新古典主义和几种异常运输模型可供选择。还考虑了产生粒子和能量的源和汇的重要物理过程，包括欧姆加热、电子离子能量交换、辐射、中性传输（和气体膨胀）、中性束加热、射频加热、颗粒燃料和聚变。
ONETWO is a one-and-a-half-dimensional, time-dependent computer code for modeling plasma transport in tokamaks. Both circular and noncircular cross-section plasmas, including doublets, can be modeled along with currents in field-shaping coils. Electrons, several species of ions, and two species of neutrals may be considered simultaneously. The electrons and ions are treated as fluids, while the neutrals are treated kinetically. Neoclassical and several anomalous transport models are available. Important physical processes that produce sources and sinks of particles and energy are also considered, including ohmic heating, electron-ion energy exchange, radiation, neutral transport (and gas puffing), neutral beam heating, RF heating, pellet fueling, and fusion.
