    各位大佬好,我是CFDEM新手,最近尝试参照twoSpheresGlowinskiMPI构建自己的算例,采用dynamicRefine,在计算过程中断构建的算例基本与参照算例一致,但试跑算例出现中断,不知道是否是哪里没有注意到,求大佬指导
    报错描述
    当不使用自适应网格时,算例正常计算;当采用自适应网格功能interDyMFoam,网格未加密前(未达到设置加密条件),正常计算;网格开始加密计算中断。
    报错代码如下:

    MPI_ABORT was invoked on rank 15 in communicator MPI_COMM_WORLD
    with errorcode 1.
    
    NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
    You may or may not see output from other processes, depending on
    exactly when Open MPI kills them.
