Greetings,

Previously, I performed a simulation in CST Studio Suite of a gridded electron gun to be able to extract electron bunches instead of continuous emission. Consider the following animation,

I would like to fix the frame at a specific time, for example this frame,

In this frame, I would like to make a location constraint. For example, I want to tell CST to consider a box around the extracted bunch (I will define the [x_min, x_max ,y_min, y_max, z_min, z_max] manually). Then I tell CST that in this fixed frame and in this fixed constraint box, extract all of the 6D Phase Space and Profile of the bunch. Unfortunately, I do not know how to do that.

Thank you for your time and consideration.

UPDATE: It seems that my extraction method is very hard since there are no answered after 1 week. Is there any way that I can have access to the bunch's information?
