Sir,
On doing K-point and Cutoff energy convergence for hexagonal system, lattice constant not changed anymore. It remains same in all calculations. Is this correct? Or, i have done any mistakes.
I use ISIF=2 in INCAR file.

ISIF=2 tag performs only geometric relaxation but not cell relaxation.
I think plz take the optimized geometry and run a single point calculation for the convergence test
