fix nvt and fix langevin

Dear LAMMPS Users

LAMMPS manual says that langevin fix should not normally be used on atoms that also have their temperature controlled by another fix like nvt.

So how will thermodynamic information differ when we use langevin with nvt and langevin with nve?

Thanks and Regards

If you use fix langevin with fix nvt it will be wrong. If you just use fix nvt, it should be comparable to fix nve plus fix langevin, given that your normal dynamics are working properly and stuff.
