Hello Dumsani,

there are two different things you may want to do. If you have files
rho.file_0.h5 eps.file_0.h5 rho.file_1.h5 and eps.file_1.h5 and would
like to combine the variables you can use:

hdf5_merge rho.file_0.h5 eps.file_0.h5 vars.file_0.h5
hdf5_merge rho.file_1.h5 eps.file_1.h5 vars.file_1.h5

ie when you want to keep the file_X structure intact. If not then you
must use the hdf5 slicer:

hdf5_slicer --out3d-cube rho.file_*.h5 eps.file_*.h5 vars.h5

Yours,
Roland
