We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I can confirm that the refractive index is correct, as it is the same for both mesh refinement options after meshing, monitored with the refractive index monitor.

Conformal variant 1:

 

Precise volume averaging (precision 11):

It is clear that the expected diffraction behavior of a sinusoidal grating is lost after meshing with "precise volume averaging".

As I would like to use the "precise volume averaging" mesh refinement for arbirarily shaped surfaces, it is unfortunately not an option to use a custom simulation object.

Is this an incompatibility between the importsurface2 function and precise volume averaging or can this problem be resolved by changing some settings?
