We address the validation of finite elements ion cyclotron range of frequencies (ICRF) antenna coupling simulation against experiments performed in the ASDEX Upgrade tokamak. Measurements of the loading resistance in ICRF-heated, magnetically-perturbed 3D plasma discharges are compared against numerical predictions of the RAPLICASOL code. To this end, the 3D induction field and the 3D density profile are modeled by concatenating the PARVMEC, BMW and EMC3-EIRENE codes. The 3D density is input to RAPLICASOL, where full-wave simulations are performed on a finite element mesh retaining full 3D geometry in the ICRF antenna model and the plasma description. The results are further compared with RAPLICASOL simulations using a 1D density profile as measured at the outboard midplane in the same experiments. We find that simulations using a 1D density profile overestimate the change in loading resistance by a factor of ∼197 − 248%, while simulations using the full 3D density profile are in agreement with experiments within a factor ∼16%.

我们将针对在ASDEX升级托卡马克中进行的实验来验证有限元离子回旋加速器频率范围（ICRF）天线耦合仿真的验证。将ICRF加热，磁扰动的3D等离子体放电中的负载电阻测量结果与RAPLICASOL代码的数值预测结果进行了比较。为此，通过串联PARVMEC，BMW和EMC3-EIRENE代码对3D感应场和3D密度分布进行建模。3D密度输入到RAPLICASOL，在其中对在ICRF天线模型和等离子描述中保留完整3D几何形状的有限元网格进行全波仿真。在同一实验中，将结果与使用1D密度分布图进行的RAPLICASOL仿真进行了比较，该密度分布图是在外侧中平面处测得的。
