thanks a lot for your answer.
It is true that I can override the mesh order from the material database, but a mesh of order 1 takes long time in the calculation (in fact, I want to put bigger discs).
I don’t know if the solution of putting the Si layer before in the objects tree will solve the problem, as suggested in the web.
I have another question, and is related with the position of the monitors, that by the way I don’t know if the ones of the file (I upload it again in this post) are the correct ones.Au_disk Si layer.fsp (281.3 KB)
If I consider only the layer, I get the following transmittance (“Trans” monitor), so if the monitor is inside gives the correct answer.
However, for the Au disc, it happens the opposite: if the monitor is outside, I get the correct spectra.
I know that you answer this in my previous post, but why is different the results for films and for a nanostructure, depending of the position of a transmittance monitor? again, is this the correct monitor to measure transmittance?
Thank you very much for your help.
