The ability to simulate neoclassical tearing modes (NTMs) in the gyrokinetic toroidal code (GTC) has been developed and verified, in which ions are treated with a gyrokinetic model and electrons are treated as a resistive fluid. The simulation results demonstrate that the neoclassical bootstrap current effect can destabilize an otherwise stable classical tearing mode. In the cylindrical geometry, GTC simulations in the magnetohydrodynamic limit show quantitative agreement with the modified Rutherford theory, both in terms of the scaling law in the small island limit and in terms of the saturation level and pressure flattening effect in the large island limit. The toroidal effects are slightly destabilizing for the NTM, while the kinetic effects of thermal ions are stabilizing for the NTM and increase its excitation threshold.
回旋动理学环形代码（GTC）中新经典撕裂模（NTMs）的模拟能力已被开发并验证，其中离子采用回旋动理学模型处理，电子则作为电阻流体处理。模拟结果表明，新经典自举电流效应能够使原本稳定的经典撕裂模变得不稳定。在柱几何中，GTC模拟在磁流体动力学极限下与修正理论在定量上一致，既体现在小岛极限下的标度律方面，也体现在大岛极限下的饱和水平和压力展平效应方面。环形几何效应对NTM有轻微的去稳定作用，而热离子的动理学效应则对NTM起稳定作用，并提高了其激发阈值。
