The SOL steps present alternatively with DAV steps.

I confirm this bug.

I have experienced the same problem, the solvent is only applied after the SCF cycle converges.
Thus, the VASPSol calculations on the GPU are useless.

Is there any plan to address this GPU/VASPSol bug?

Dear VASP users and developers,

For anyone looking at this bug, as it is not clear if it is on the VASP side or the VASPSol plugin side, I have also reported at the VASPSol github project: https://github.com/henniggroup/VASPsol/issues/40

I hope someone looks at this bug, using the CPU version feels sluggish after experiencing the VASP on GPU.

Dear all,

The bug seems to be fixed for VASP 6:
