Dear PwSCF users,<br>I am want to do calculation of SiO2. <br>What I want is to optimise the structure, using vc-relax. Beside I also want that, the angle should not change between the atoms and vc-relax give me an optimised structure.<br>
So is it possible? If so then what i have to modify in my input file? Means what additional string I have to add.<br><br>I am sending my input file for vc-relax.<br>thanks<br clear="all"><br>-- <br>Bipul Rakshit<br>Research Fellow,<br>
