I want to check the pressure induced structural and magnetic properties changes in a system. How can I do that in VASP? How can I apply pressures like 2 GPa, 4 GPa, 6GPa etc?
Add PSTRESS= "pressure value in kbar" to the INCAR. For instance PSTRESS= 10.00000 for 1GPa. If you have a wide range of pressure and more than 5-6 pressure points, you can write a script to automate the procedure.
