Hello Chia-Hui,

> So generally , how can we combine output data of  output000* together?
Cactus builds a tool hdf5_merge that can do this. You can find it in
exe/sim/hdf5_merge and you would use it like so:

exe/sim/hdf5_merge output-0000/rho.file_*.h5 output-0000/eps.file_*.h5 output-0001/rho.file_*.h5 output-0001/eps.file_*.h5 combined.h5

Yours,
Roland
