<meta http-equiv="Content-Type" content="text/html; charset=utf-8"><p dir="ltr">A small clarification. This :WARN arises from a useful addition by Peter to test the convergence of the core forces in lcore. If the RMTs are small, and for some reason with mBJ, there is a tail of the core wavefunction outside the RMTs. This would lead to small errors in the minimizations using MSR1a or PORT.</p>
<p dir="ltr">Currently mixer prints this out whether or not you are minimizing; I am considering only printing the :WARN for a minimization. If you are not optimizing positions you can ignore it.</p>

is only a potential (no associated energy) that should be used only for<br>
band structure. Run a mBJ calculation only at a fixed geometry<br>
