Hello Seyed,

  1.  Is there a reason the electrodes and scattering regions are not 
connected? Is it relaxed in SIESTA?
  2.  Is there a reason you chose DM.OccupancyTolerance   0.1000000000E-11 that 
is very small to be honest. Also DM.Tolerance           1.d-5 also seems very 
small I would cut it down to 5.d-3. Also It seems a complicated system so go 
for a  MaxSCFIterations        10000

Hope that helps!

Subject: [SIESTA-L] Transiesta DM does not converge

Dear all,

I am doing a TranSIESTA calculation for the following system.

[cid:[email protected]]

However, I cannot converge the density matrix no matter how small my mixing 
weight is.

I would be grateful if you help me with it. My output file is also attached.

Best regards,
