Hello everyone,
I'm tryint ot calculate the work function of a metal slab and I
successful did that on a 100 facet of the respective metal.
But I'm getting an error when I run pp.x computation on a 110 facet system.
When I run pp.x,  I run into the error below:

 Error in routine chdens (1):
     nx,ny,nz, required
What does it really mean or what could be wrong?
How do I resolve it please?

Thank you.

Kind Regards,


Thank you.
