But in the case of ultra soft pseudo potentials it is different. For example if my system consist of Nb and Sn elements, i can get <a href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/Nb.pbe-nsp-van.UPF" target="_blank">Nb.pbe-nsp-van.UPF</a> for Nb element and <a href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/Sn.pbe-dn-rrkjus_psl.0.2.UPF" target="_blank">Sn.pbe-dn-rrkjus_psl.0.2.UPF</a>, <a href="http://www.quantum-espresso.org/wp-content/uploads/upf_files/Sn.rel-pbe-dn-rrkjus_psl.0.2.UPF" target="_blank">Sn.rel-pbe-dn-rrkjus_psl.0.2.UPF</a> for Sn element. Different methods are used in developing these potentials. <br>
<br></div><div> Now my question is, can i use these potentials in my calculations?. If i use one NC and one ultrasoft what will happen?.</div><br></div>Thank you in advance...<br></div>
