Title: miscellaneous: spatial regions
Post by: Wisam1222 on December 10, 2020, 11:11

Hello
I used the spatial regions to project an electric field (miscellaneous: spatial regions).
But I noticed an effect of the added spatial regions on the band gap even though the voltages were 0 for both regions.
Is there a way to avoid this effect?
Please help me in this matter

Can you provide the input script?

Do you confirm the exact calculation settings between configuration with spatial regions and configuration without spatial regions?
If you use default condition for above two configurations, default setting will be different in two cases. (For instance, poisson_solver)
