大家好!
我最近在用WRF3.9.1进行模拟计算,主要想使用其中的轨迹计算功能。我使用三层嵌套模拟,根据我的理解,需要建立三个wrfinput_traj_<domain>文件,./real.exe这一步是可以成功的,但是在运行wrf.exe时,转几秒就断掉了。检查rsl.error.0000文件,出现forrtl: severe (174): SIGSEGV, segmentation fault occurred 这个错误。
我在网上查了相关问题,主要解决方案有两种:一是把时间步长改小;二是在wrf.exe之前使用“ulimit -s unlimited”命令。进行尝试后均没有起作用。
我之前在用单层嵌套进行试验的时候,只添加wrfinput_traj_d01一个输入文件是可以正常运行的。三层嵌套的时候只有wrfinput_traj_d01也是可以的,但是这样d02和d03就不发进行轨迹计算了。
不知道大家有没有遇到过这样的情况,或者有没有人使用过WRF里的这个功能,恳求大家的帮助!谢谢!
