Then some path testing may be needed, as the current code seems to require Bellhop.exe and .py to be in the same folder, otherwise the output file cannot be detected, or move from the path of file to the path where .exe is located during calculation and plotting.

There is no special requirement of where bellhop.exe is, as long as it in on your PATH.
