Hi everyone,

I'm running a geometry optimization simulation of a AlFeSi cell. The simulation will not converge, and when I try to output the trajectory to see what is wrong, it will not print the trajectory. Can anyone give me some hints on what might have gone wrong?

Best,

Hi Anqi

 

Such problems are often caused by improper atomic coordinates or cell lattice vector definitions. Check the output for small interatomic distances or other warnings.

 

Best,

 

Matthias
