[MCNP6] How to use Tally E with Fmesh

[DONGY]

Hello everyone,
I do need your help in this matter, please kindly help me solve this problem.
I use MCNP5 and i want to use Tally E with Fmesh.
I use Tally E and Fmesh this way with MCNP5.

F4:P,E 6
E4 0 200i 2
FMESH4:P GEOM=REC ORIGIN=-550 -550 -1
      IMESH=-50 IINTS=5
      JMESH=550 JINTS=11
      KMESH=799 KINTS=8
      EMESH=2

But I want to use Fmesh in MCNP6. I don't know how to write it.
Such as this.

FMESH4:P GEOM=REC ORIGIN=-550 -550 -1
      IMESH=-50 IINTS=5
      JMESH=550 JINTS=11
      KMESH=799 KINTS=8
E4 0 200i 2

Please, help me

Hi,

E4 would follow an F4 tally.
To do the same thing with an FMESH4, put the energy values you would put in an E4 into the EMESH= section which exists in your first example but is missing in your second.
Like this

FMESH4:P GEOM=REC ORIGIN=-550 -550 -1
      IMESH=-50 IINTS=5
      JMESH=550 JINTS=11
      KMESH=799 KINTS=8
      EMESH=0 200i 2

This is the same for MCNP5 and 6.
,
I hope this helps.
