<div dir="ltr">hi all <br> i tried to run the following input file with C2 symmetry using slapaf paritial optimization it runs upto single point calculation and when it comes to optimization statge<br>it simply is running but no output is seen in the output file for very long time i like to know if this slapaf method takes such a long time to optimize becasue i want to fix four dihedral angle<br>
or is it a sign of hanging due to insufficient memory or wrong commands or syntax can any one run this file in their system to see if everything is alright <br><br>***,quinone<br>!memory,64,m<br>gprint,basis,orbital<br>geomtyp=xyz ! use cartesian coordinates xmol style<br>
