energy convergence issue in perovskite LaMnO3

[Monika srivastava]

hi team

I am trying to do energy convergence of LaMnO3 R-3C H  by taking cif file from materials project but its not converging to given criteria even 300 steps and because of that high i am getting low TE at low Ecut and high TE at high Ecut

HI
Do u mean electron convergence or atomic force convergence?

For former, decrease the damping factor to 0.01 &/or history steps to 12.
For latter, try rattling of atoms around mean position.
