TPOT is a Fortran code that enables Grand Canonical simulations of liquid/solid interface with Density Functional theory by controlling number of electrons in the simulation supercell so that the work function reaches a target value. It runs with the VASP code and VASPSol package.

1️⃣ Make nessesary changes to source of VASP code

Follow the instruction for making change in vasp code.

2️⃣ Update VASPSol

Download and follow instruction at https://github.com/zoowe/VASPsol/

3️⃣ Copy main source code

Copy src/targetpot.F to vasp src folder

4️⃣ Recompile your vasp code

Detailed instructions and examples are available at TPOT's mannual
