摘要

针对 EU-DEMO 几何结构中的流体中性平均场等离子体边界模拟进行了网格细化研究。一般来说，模拟的网格收敛是可以实现的，对于大多数相关量，最细网格和次细网格之间的差异为 <5%。原始 96 × 36 网格的离散化误差估计值大多在 4%-25% 之间。不过，由于等离子体边界代码的非线性性质，也可能出现例外情况。因此，建议定期对子集案例进行网格细化研究。

Discretization error estimation for EU-DEMO plasma-edge simulations using SOLPS-ITER with fluid neutrals

A grid refinement study is performed for mean-field plasma boundary simulations with fluid neutrals in an EU-DEMO geometry. In general, grid convergence of the simulations is achieved, with differences between the finest and second-finest grid of <5% for the majority of the quantities of interest. The estimated discretization errors for the original 96 × 36 grid are mostly in the 4%–25% range. However, it is also shown that exceptions are possible due to the non-linear nature of plasma boundary codes. Hence, it is advised to regularly perform grid refinement studies on subsets of cases.
