Hi,

I am working on project which involves energy calculation of chromium (cleaved surface). 

Which forcefield will work in this case, generally after energy calculation I get charges on each atom and then I use that surface to do further molecular dynamics. 

With Fe, universal with gasteiger charges worked but in chromium i am getting error messages saying gasteiger charges are not parameterized for Cr.  QEq is not for surfaces.

My current license doesn’t have COMPASS.

 Thank You
