[QE-users] Calculation of kinetic energy

[ALFONSO GALLO BUENO]

Dear all,
I am using QE - 7.2 compiled with libxc to calculate the kinetic energy through the pp.x code and plot_num=22.
Before this calculation I perform a SCF calculation with norm-conserving PPs.
As specified for plot_num=22, in order for the kinetic energy density to be calculated I need a meta-GGA and XDM calculation.

However, if I use both a meta-GGA functional (e.g.: scan) together with vdw_corr='xdm', it fails with 'not implemented' message.
If I do not use vdw_corr, just the scan funcional, the calculation finishes successfully but pp.x prints an empty (all zeros) kinetic energy cube. Tried with other metaGGA and non-metaGGA functional, also with empty kinetic output.

Attached input files for both the pw.x and pp.x calculations for urea crystal.

Thanks a lot for your help!
