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?
