最近在做高精度的数值模拟,用WRF4.1模拟一次龙卷个例,最内层分辨率50m,采用的ndown,最外层4km,一共5层单向嵌套,前四层的模拟都没有问题,就是50m的模拟,总是算到一定时间就跳出,也不报错,很疑惑这个问题。
针对该问题做出的尝试:(1)单独拿出50m做一次单层的模拟,也是一样的问题,不报错,到一定时间任务就跳出。(2)尝试换过微物理方案8和10,长短波方案1和4,问题没有变化(3)继续减少积分步长,0.1s试过,还是同样的问题,不过模式跳出的时间不一样,但都是基本第一个小时没转完就跳出了,没有报错
跟老师讨论说是积分溢出,想知道怎么解决这个问题,各位老师同学有遇到过类似的问题吗?
附上namelist.input和rsl报错文件
