By comparing the simulation results of CLT code and M3D-C1 code, it was found that they were almost identical in terms of resistive kink mode and tearing mode, including linear and nonlinear growth rates. This indicates that the simulation results for the 1/1 resistive-kink mode and 2/1 tearing mode are accurate and reliable.
The linear and nonlinear benchmarks between the CLT code and the M3D-C1 code for the 2/1 resistive tearing mode and the 1/1 resistive kink mode are presented. CLT is an explicit finite difference code, while M3D-C1 is an implicit finite element code. Although the implementations of CLT and M3D-C1 are totally different, we find that the simulation results of the resistive-kink mode and the m/n = 2/1 tearing mode from M3D-C1 and CLT are almost the same, including the linear and nonlinear growth rates, the mode structures, the nonlinear saturation levels, the Poincare plots, and the scaling laws. This confirms that the nonlinear results for the 1/1 resistive-kink mode and 2/1 tearing mode are accurate and reliable. (C) 2021 Elsevier B.V. All rights reserved.
