<div dir="ltr">Hello there,<div><br></div><div>I am trying to use the MGGA r2SCAN functional from Libxc with the rVV10 non-local term. For this, I'm using this as input_dft:</div><div><br></div><div>'XC-000I-000I-000I-000I-497L-498L-vv10' <br></div><div><br></div><div>as described in the user's guide. With this, the output says that the parameter b (from rVV10) used is 15.7. However, a few things are odd.</div><div>First of all, this value of b is the default of the rvv10-scan functional (as seen in the Modules\funct.f90 file). But this is not what I'm looking for; I want to use the "pure" rVV10 functional term with another functional.</div><div>Secondly, when the input_dft is</div><div><br></div><div>'XC-001I-004I-013I-000I-000I-000I-vv10' <br></div><div><br></div><div>the b value showed on the output is 6.3, the default of the "pure" rVV10 functional. Indeed, when the input_dft is 'rvv10', the same value of b is used.</div><div><br></div><div>So here are my questions: </div><div>1) how do I put the "pure" rVV10 and the r2SCAN functionals together in the proper way?</div><div>2) is there any way to change the default value of b? (this, in fact, is what I need the most).</div><div><br></div><div>Best regards,</div><div><br></div><div>Ricardo Cecconello,</div><div>Universidade de Caxias do Sul</div><div>95070-560 Caxias do Sul - RS - Brazil </div><div><br></div></div>
