大家好,我又来了。
最近在做一个关于WRF初始场的滤波试验。主要过程是首先./real.exe生成三个wrfinput(我是三重双向嵌套)和一个wrfbdy,然后分别对三个input的高度场、风场进行barnes带通滤波,用滤波后中尺度场分别对d3,d2、d3,d1、d2、d3的input文件相应部分进行替换,最后驱动模式模拟。
那么现在问题来了:仅替换d3以及替换d2、d3后./wrf.exe都能顺利转完,但同时替换d1、d2、d3后没转多久就出现segmentation fault :core dumped错误,网上有说是数组越界错误,我检查了d1高度场、风场的数组大小,比对了下也没发现前后有出入。不知道是不是与最外一层区域初始场要和边界场协调或是其他什么物理、动力原因相关,而非单纯的计算、内存错误?还请各位帮忙分析下,谢谢!
贴出log和嵌套设置图:
