Hello everyone,

I am a beginner with NWChem and computational chemistry.

I am trying to do a CDFT task on a simple nitrogen molecule.

I am running into convergence issue, both the script and the output file is listed below.

Can anyone take a look at them and tell me what I am doing wrong? I am sure that I am doing many things wrong.

Thank you in advance.

Script:
start nitrogen

geometry  
  n 0 0 0
  n 0 0 1.08
end

basis
  n library 6-31g
end

dft
	VECTORS output nitrogen.movecs
	XC b3lyp
	CONVERGENCE energy
	CONVERGENCE density
	CONVERGENCE gradient
	CONVERGENCE nolevelshifting
	GRID xfine
	ODFT
	MULT 1
	CDFT 1 1 charge 1.0
end

task dft

dplot
	TITLE Density
	vectors nitrogen.movecs
	LimitXYZ
		-3.0 3.0 10
		-3.0 3.0 10
		-3.0 3.0 10
	spin total
	gaussian
	output nitrogen_density.cube
end

task dplot


The last few lines of the output file:
 
 ------------------------------------------------------------------------
 dft energy failed                                                                                  0
 ------------------------------------------------------------------------
 ------------------------------------------------------------------------
  current input line : 
    25: task dft
 ------------------------------------------------------------------------
 ------------------------------------------------------------------------
 This type of error is most commonly associated with calculations not reaching 
 convergence criteria
