wrf模式使用相同参数,不同区域导致无法运行。第一组区域能够正常运行,第二组区域无法运行下去,错误提示如下:

第一组区域如下:

e_sn = 65, 97, 118, 169,
dx = 9000, 3000, 1000, 333.333, 111.111,
dy = 9000, 3000, 1000, 333.333, 111.111,
第二组区域如下:
e_we = 61, 91, 127, 181,
e_sn = 61, 88, 121, 163,
dx = 7290, 2430, 810, 270,
dy = 7290, 2430, 810, 270,
***************************************
开始是四层嵌套,第一组没问题,第二组则不能运行,试过减少层数,也使用了ulimit -s unlimited,没有cfl溢出问题,真的没办法了,期待有遇到过类似问题的给点意见。
ps:程序在超级计算机上运行,内存应该没有问题的。
