fix command for two types

Hi Dr. Axel, Dr. Steve and all users,

I am simulating two types of atoms in one simulation, lets say Fe and Pb.
Using "FIX COMMAND" I want to see the result in two log files as below:

log_Fe.dat:

Fe Step PotEng Temp Volume TotEng Press Lx Ly Lz Xlo Xhi Ylo Yhi Zlo Zhi
........................................................................
........................................................................

log_Pb.dat:

Pb Step PotEng Temp Volume TotEng Press Lx Ly Lz Xlo Xhi Ylo Yhi Zlo Zhi
.........................................................................
.........................................................................

My question, Is it possible to do that? How is the way to write a command in input's script?
Do you have any suggestion?

Thanks very much for answer.

Best Regards

no - you get one set of thermo output for your run. You can have
fields in that line that are specific to Fe or Pb, assuming you set
up variables or fixes or computes that work on one or the other.

See Section 4.15 of the manual for more info on tailoring output
of LAMMPS.
