[QE-developers] Bugs in SCAN0 with QE6.3 6.4 6.5

[Chunyi Zhang]

Dear colleagues,

I met with some problems when I try to run SCAN0 SCF calculation with
QE6.3, QE6.4 and QE6.5.

When I use QE6.3 and QE6.4, I get the CRASH information "wrong igcx and/or
igcc". I noticed, in Modules/funct.f90, when imeta==6 (which is for scan0),
it "call errore('tau_xc', 'wrong igcx and/or igcc', 1)". Does it mean that
QE6.3 and 6.4 can not run SCAN0.

When I use QE6.5, I get an output file tells me that SCAN0 has been turned
on. But it does not conduct the real EXX calculation.

Could anyone give me some help please?

Attached is my QE6.5 SCAN0 input and output file.

Best Wishes!
ANNA ZHANG
