[BonnMotion] In Range Printer output times exceed duration

[Thomas Jordan]

Hi,
I have recently started generating RandomWaypoint scenarios using BonnMotion and then using the In Range Printer application to analyse the results and I now have two questions.

First question: I notice that when I run the In Range Printer on a scenario, maximum times in the output of the IRP exceed the duration of the scenario. For example, if I run a scenario for 1500, I see max waypoint times in the movements.gz of 1500.0 which looks correct, but see max times in the .irp file of 5076.121483475256.

Can anyone explain to me why this is happening?

The .param file for this scenario is as follows:

model=RandomWaypoint
ignore=3600.0
randomSeed=3
x=500.0
y=500.0
duration=1500.0
nn=64
circular=false
J=2D
dim=4
minspeed=2.0
maxspeed=4.0
maxpause=0.0

Second question: the generation of the IRP file from a scenario seems to take a long time. For the above scenario, I see times 2.5 - 3 hrs on an Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz with 32 GB of RAM (Windows 11, Java v21.0.1). Is this apparently long run-time for IRP herer simply because of the computational time taken to do the physics/motion calculations (which I assume is some calculation of moving point colliding with moving circle and emerging from the circle while both are still moving), or is this something I can do to reduce it?

Regards,

Tom
