Dear all,
I used the ascii2h5block tool included in OPAL 2022.01 to successfully convert
the 3D electric and magnetic field data. The command is
'ascii2h5block efield.txt hfield.txt efouttool'.
After using the BANDRF type to input file, I used OPAL-cycl mode to track
single particle first. It was found that the energy of the particle had no
change, just like there was no electric field. Using the DUMPEMFIELDS command
to output the electric field, it was found that the electric field values at
all points were indeed 0, but the data in the efouttool.h5part file I read was
intact. I have verified it with HDFView. Why i have this problem? I am a
freshman to use OPAL, and I hope someone can help me. Thank you very much!
