Hi NWChem folk,

I run constrained DFT with combining multiple fragment MOs guess files. Here is my input & output [1]. During CDFT calculation process, I got the error message CDFT: Unable to improve the multipliers'. I googled the solution but I found that nobody in NWChem forum has mentioned about this issue before. Please suggest me what caused this error and the way to overcome it.

Your help would be appreciated for me.

Thank you.
