<p>Dear Quantum Espresso Users,<br>
</p>
<p><br>
</p>
<p>I am interested in calculating the dielectric tensor for a metal oxide. However, I am uncertain how to proceed with this calculation. <br>
</p>
<p>Based on my knowledge, I know that Hubbard U corrections are typically needed for metal oxides in order to predict the correct insulating behavior. However, if I describe the system as a metal (with smearing and a degauss value) with Hubbard U then the code
may lead to an error because the dielectric constant for a metal is infinite.</p>
<p>Is there a way around this problem? Any advice would be greatly appreciated. <br>
</p>
