IBAMR重启

./main3d ./input3d ./restart_ IB3d 200000 这里./restart_ IB3d 是包含所有重启数据的目录， 200000是最大数字。参考

hier_data_ib2dStr文件夹内包含重启类型的文件。

在重启中似乎对于INS求解器，如果重启发生在原始模拟中重新网格化完成的点，就会出现与优化调度相关的段错误。也就是说，如果regrid_interval和restart_interval，在同一个时间步下出现，就会出现问题，目前就是避免这两个在相同时间步下实现

IB似乎没有这种问题，只有ConstraintIB 出现了。 “好的，这是因为力没有被输出——这扰乱了确定是否应该在重启时记录力的逻辑。现在正在修复并测试。” “我明白了。我们通常不会在 ConstraintIB 方法中输出力，因为它没有任何物理意义。它的总和是有含义的，它会被打印在文本文件中。 ”

看来好像问题解决了

./main2d input2d /restart_IB2d 70

是可行的命令
