[Pw_forum] pp.x Error in routine chdens (1): nx, ny, nz, required

[黄志硕]

Dear all,
I am calculating the work function following the example in $PWscf-5.1.1_DIR/PP/examples/WorkFct_example. When I perform the calculation by "./run_example", everything is fine. But when I did my own calculation with the similar input like the WorkFct_example, there was an error in the output file of the pp.x, which is named pp.out by me:

According to the input_pp documentation, there is no need to include any of nx, ny, and nz variables in pp.in file.
And I have search on the internet, and find something(https://www.mail-archive.com/pw_forum@pwscf.org/msg24783.html), but it did not specify how to solve this problem.
I will appreciate it if anyone could give me some instructions


Yours sincerely
