I'm getting segmentation fault when running p2y with Quantum Espresso input input_dft = 'vdw-df-obk8':

Following the related issues above and since I'm using PBE pseudopotentials, I was able to get pass the segmentation fault by changing data-file.xml from
Code: Select all
<EXCHANGE_CORRELATION>
<DFT type="character" size="1" len="20">
VDW-DF-OBK8
</DFT>
Code: Select all
<EXCHANGE_CORRELATION>
<DFT type="character" size="1" len="20">
PBE
</DFT>
- Are there any reasons why vdw-df-obk8 functional isn't supported?
- Does my fix above affect later Yambo GW calculations?
