Dear all, <\/p>\n

Has anyone ever had an issue creating a structure with multiple holes in Lumerical CHARGE? <\/p>\n

My final structure should be a SiO2 layer with multiple InP holes. To do this I set for SiO2 mesh order 2 and for InP mesh order 1. However, it looks like only one of my structures is well reproduced ( one over three) and the well-done one is always at the bottom of the tree of the simulation region. The reason why I’m wondering this it’s because I need to compare the square lattice and hexagonal lattice displacement of the holes. In the case of the hexagonal one, I will need to put multiple objects with the same mesh order. <\/p>\n

See attached below my example. A smaller unit cell with one hole is giving me different results compared to this one, where the unit cell is bigger but I have multiple holes of the same dimension. I can see that in the cell where there is only one hole the results are correct and the hole is generated as the one here at the bottom of the tree. How can I fix this in the bigger one? Thanks in advance<\/p>\n
