交叉比较和验证的国家的最先进的欧洲代码描述梯度驱动的等离子体湍流的核心和边缘区域的托卡马克，在EFDA的综合托卡马克建模工作组内进行。在核心离子温度梯度（ITG）驱动的湍流与绝热电子（忽略被困粒子）的情况下，良好/合理的协议被发现之间的各种gyrokinetic/gyrofluid代码。讨论了在非局域模拟中观察到的一些偏差的主要物理原因。边缘模拟同意非常好的碰撞缩放和可接受的β缩放（低于MHD边界）冷离子的情况下，也在非线性模式结构。
A cross-comparison and verification of state-of-the-art European codes describing gradient-driven plasma turbulence in the core and edge regions of tokamaks, carried out within the EFDA Task Force on Integrated Tokamak Modelling, is presented. In the case of core ion temperature gradient (ITG) driven turbulence with adiabatic electrons (neglecting trapped particles), good/reasonable agreement is found between various gyrokinetic/gyrofluid codes. The main physical reasons for some deviations observed in nonlocal simulations are discussed. The edge simulations agree very well on collisionality scaling and acceptably well on beta scaling (below the MHD boundary) for cold-ion cases, also in terms of the non-linear mode structure.
