Please refer to journal paper from S.J.P.Pamela, titled "Neural-Parareal: Self-improving acceleration of fusion MHD simulations using time-parallelisation and neural operators" Available on ArXiV and on Comp.Phys.Comm.: https://doi.org/10.1016/j.cpc.2024.109391 Data produced by the JOREK code, https://jorek.eu All runs created using the RMHD model, model-ID "model600", with option with_vpar = .false. Data downsampled by saving every 10th timestep, on a regular 2D grid of 100x100. To reproduce full runs, use corresponding input files. Note: variables names are the same as in the JOREK code: u = electric potential omega = toroidal vorticity rho = density T = temperature psi = poloidal magnetic flux zj = toroidal current The create_gif.py can be used to convert data into movies.

请参阅S.J.P.Pamela发表的期刊论文,标题为《Neural-Parareal:利用时间并行化(time-parallelisation)与神经算子(neural operators)实现聚变磁流体动力学(Magnetohydrodynamics, MHD)模拟的自改进加速》。该论文可在ArXiv及Comp.Phys.Comm.获取,链接为:https://doi.org/10.1016/j.cpc.2024.109391。 本数据集由JOREK代码生成,其官方网址为https://jorek.eu。所有模拟运行均采用相对论磁流体动力学(RMHD)模型,模型标识符为"model600",且设置with_vpar参数为逻辑假值。 数据已进行下采样处理:每10个时间步保存一次数据,最终得到的数据集为100×100的规则二维网格。如需复现完整的原始模拟运行,请使用对应的输入文件。 注:变量名称与JOREK代码中的定义完全一致: u = 电势 omega = 环向涡量 rho = 密度 T = 温度 psi = 极向磁通量 zj = 环向电流 可使用create_gif.py脚本将数据集转换为视频文件。
