Geometry optimization in ATK-SE
« on: April 5, 2012, 09:00 »
 Dear sir,


         Today morning i run the program with Slater-Koster model by choosing DFTB and Hotbit separatly even though  i face same problem.If you don't mine sir,please sir once you run program for geometry optimization(Z-2-BNNR-clB-clN or Z-2-BNNR-clF-clF)  then you came to know what problem is there. Program i run in the morning that is terminated abnormally with worning message which is shown below

Hotbit doesn't have parameters for Boron. DFTB does, if you have obtained parameters from http://dftb.org then you can use the "matsci" library according to instructions similar to those in http://quantumwise.com/documents/tutorials/latest/DFTB/index.html/.
