 Also notice that command "fix plumed" should be used in lammps input
 file *after* the relevant input parameters have been set (e.g. after "timestep" command)
 
+\bug The provided patch does not pass the virial correctly to PLUMED (see https://github.com/plumed/plumed2/issues/377).
+     If you need to perform constant pressure simulations you should download a LAMMPS version newer than November 2018, where the mentioned bug
+     has been fixed, that natively supports PLUMED 2.4.
+     If you need to use LAMMPS with fixed virial with PLUMED 2.3, you can compile LAMMPS with PLUMED 2.4 using runtime binding and then set the variable
+     PLUMED_KERNEL to load PLUMED 2.3.
