ADAPTIVE time STEP CONTROL FOR multirate INFINITESIMAL METHODS
收藏 引用
SIAM JOURNAL ON SCIENTIFIC COMPUTING 2023年 第2期45卷 A958-A984页
作者: Fish, Alex C. Reynolds, Daniel R. Southern Methodist Univ Dallas Dept Math Dallas TX 75275 USA
multirate methods have been used for decades to temporally evolve initial-value problems in which different components evolve on distinct time scales , thus use of different step sizes for these components can result ... 详细信息
