Dear Elie,

Can you provide please your input file for the pw.x code?

Greetings,
Iurii

Subject: [QE-users] Turbo_eels.x crashing

Dear all,

I am trying to calculate the absorption spectrum using the turbo_eels.x toolset . My system is metallic and has noncollinear spin-orbit coupling switched on, which means I cannot use neither turbo_davidson nor turbo_lanczos. For that matter , my  turbo_eels input is :

&lr_input
prefix='pds'
outdir='/'
restart_step=50
restart=.false.
/
&lr_control
calculator='lanczos'
itermax=500
q1=0.001
q2=0.000
q3=0.000
/

The code starts by doing an nscf calculation but , right after that, it crashes. Looking at the error file, I found the following:

program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:

Can anyone please let me know how to circumvent this error?

Thanks in advance
