Proper way to restart geometry optimization


Clicked A Few Times
Hello,

I'm having problems restarting my geometry optimization jobs. I initially supplied the input coordinates and ran the optimization for 5 steps before the job canceled. However, when I try to restart the job using the restart keyword, it says no geometry was found. Any guidance on how to properly make a restart file would be very helpful. See my file below. Thanks!


argument  1 = restart.nw

By using the keyword start in your input file, you have wiped clean the results from the previous calculation. The keyword you should have used is restart, instead
