ERROR: charge density could not be read from file CHGCAR for ICHARG>10

[Joseph Kaore]

Hello, I am trying to run a DOS calculation for the surface of Perovskite how ever I'm getting the following error:

LDA part: xc-table for Pade appr. of Perdew

 WARNING: stress and forces are not correct

 POSCAR, INCAR and KPOINTS ok, starting setup

 WARNING: small aliasing (wrap around) errors must be expected

 FFT: planning ...

 WAVECAR not read

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 WARNING: dimensions on CHGCAR file are different

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

 ERROR: charge density could not be read from file CHGCAR for ICHARG>10

I copied the CHGCAR from the SCF calculation with CONTCAR from the relaxation calculation to a new directory along with the universal KPOINT file and edited the INCAR file with the inclusion of the tags LORBIT = 11, NEDOS =1000 and changed ICHARG = 2 to  ICHARG = 11.

I'm not sure why this error came about, can someone help?

i think (though not sure) the FFT grid is not matching in both cases.

Pickup NGX, NGY, NGZ from SCF calculation and declare them manually in subsequent calculations/run. and see if there is any luck !!!
