CST - PS PIC solver problem

We use PIC solver to simulate the particle inside cavity. We use CST particle import interface function to import pid file. We try to get the phase space distribution on percific time frame and we face some problem.

Q1: we don't understand the current definition inside the pid file format. Can someone help to expain it? thank you.

Q2:After finishing simulation, We found the particle number increase after time increased(time frame 99.png). Is it right?

Q3: Also, the particle distribution is wrong and different from handbook example(handbook exmple.png). Why is the particle not a discrete distribution? the result seems to combine all the result of each time frame.

Thank you
