---- INFO ----

Modified integration in component acoustic 1 has the value 0

---- FATAL ----

The flow seems to be supersonic on some places. It is advised that you check your input file. Those values can be modified by setting the command line argument to a value between 0.9 and 1. The supersonic values higher than (cut_sos times the local s-o-s) will be cut to this value.

A:
      FTP上培训资料，海基自备的morhing声类比案例中，部分流场流速是超音速。在计算时需要输入命令将超音速流转换为亚音速计算。
      例如输入 -m 2000 --cutsos 0.99
      即将超音速流转换为0.99马赫数 --cutsos : allows to replace the supersonic values of the mean flow by a valueequal to the provided ratio times the speed of sound。
