How to calculate Electric field at arbitrary point

Please login with a confirmed email address before reporting spam

Hello Everyone...
I have designed a model in which light is scattered by a gold nano particles.

Now i want to calculate the value of scattered electric field at any arbitrary point.

Can anyone tell me how to calculate it and export this data??

Before solving the problem you have to add points in your geometry (if needed) where you want to calculate the said variables. After simulation, Derived Values --> Point evaluation.

Is this what you asked?

If the quantity is needed only for post-processing purposes, you do not have to add a point to the geometry: you can add a Cut Point data set and then perform a Point Evaluation on that data set.

Suppose i simulated the scattering model for nanosphere. Now i want to calculate the electric field scattered by any nano sphere at any point (obviously inside the PML domain). So how cn i calculate this ??
