follow is vasp admin's voice:

this message says that during geometry optimisation no reasonable next step could be found with Brent's algorithm (linear bisectioning)
please check the following
1) is the system converged already? (look at the forces in OUTCAR, especially if you use the total energy change as congvergence criterium for ionic optimisation)
2) if not: is each ionic step converged electronically ( this is needed to obtain reasonable forces)

真理是一点点接近的!

我一般用方法2(ibrion=2)的时候的才出现这个情况,换成1就好了。
一以贯之
