A method of reduction of the two-dimensional equation for the potential to a one-dimensional ordinary equation is suggested and implemented in the B2SOLPS5.0 transport code to simulate a divertor tokamak. The one-dimensional version, which gives similar results as the full two-dimensional version, provides better understanding of the role of various mechanisms of perpendicular conductivity and reduces computational time. The scheme of poloidal (parallel) current calculation is presented and compared to the two-dimensional code results both for the core region and for the scrape-off layer.

2次元方程式から1次元常微分方程式への簡約方法が提案され、ダイバータ・トカマクをシミュレートするためにB2SOLPS5.0輸送コードに実装された。完全な2次元版と同様の結果を与える1次元版は、垂直方向の伝導における様々なメカニズムの役割の理解を深め、計算時間を短縮する。ポロイダル(平行)電流の計算スキームが提示され、コア領域とスクレイプオフ層の両方について2次元コードの結果と比較された。
