Job ID: 38070974

Budget: $30 – $250 USD

Hello, I need help with LAMMPS. I'm looking to perform a Monte Carlo simulation on a zirconium-copper cube with a concentration of 2%.
I don't get along with the Monte Carlo execution setup I don't get replacements of atoms
I have attached an article, see Figure 1 on page 10
