Did you set the "ntwe" variable? The default is not to write mden
files. (Be sure to read the explanation of ntwe in the manual, which
describes a reason why mden files are rarely requested.)

Most people parse the mdout file: see the script as an
example. The "energy" action in cpptraj can also be used to get
energies if you save the coordinates in a trajectory file.
