I’ve created a structure of water droplet falling into Cu surface using material studio. I’m trying to convert material studio file using msi2lmp into lammps lmp data file. But, I’m getting this:
Running msi2lmp v3.9.9 / 05 Nov 2018
Forcefield: Class I
Forcefield file name: /usr/share/lammps/frc_files/cvff.frc
Output is recentered around geometrical center
Output contains style flag hints
System translated by: 0 0 0
Reading car file: Cu_H2O.car
Reading mdf file: Cu_H2O.mdf
Building internal coordinate lists
Reading forcefield file
Get force field parameters for this system
Unable to find mass for xx
No datafile has been created. I’ve seen that in older version of material studio, they’ve got a module named Discovery tools, in which they’ve converted it to cvff forcefield. But, in newer version of materials studio, this module is absent. How can I use msi2lmp or another module in material studio 2020?
