Following is one section of the output. Remaining part is similar to this, the simulation keeps on running:

Why does it keep running?

Welcome!

From looking at the output:

WARNING: type information on POSCAR and POTCAR are incompatible

it looks like you defined types in POSCAR in a different order than POTCAR. So the structure you're trying to relax isn't close to the starting structure. It probably will never relax.

Double check the order of the data in POTCAR vs POSCAR. If they are wrong, swap them and let us know if this fixes it!

    $\begingroup$ I swapped the 2, still got the error. However, I checked and found that my structure had somehow changed from hexagonal to cubic when converting from vesta to POSCAR format. Also, I reduced the NSW to 800, not sure if this had any effect, but my calculation converged. $\endgroup$ Commented Jul 20 at 5:18
  • $\begingroup$ If you still got the error, something else must be wrong too... make sure you are using the correct POTCAR datasets and they are in the correct order. Either way, glad you got it sorted out :) $\endgroup$ Commented Jul 22 at 20:38
