[Gate-users] Source error message

[vcai6204 at uni.sydney.edu.au]

Hi, 

I also found this error recurring quite often even though I did not have any overlapping. 

In my version of Gate 6.1, this mistake occured when a cylindrical shape was embedded into another cylindrical shape - like a donut within a smaller donut. The way i resolved it was by adding 1 nm to my distance so they don't overlap anymore, which for me was quite convinient, but for other such a distance may matter. 

Good luck. 

Vincent.

Hi,

Are you using the confine option? The message is telling you that after trying 100,000 times, it still has not generated a particle that is within the both the confinement volume and the source volume. The message explains that this happens if your confinement volume is too small with respect to your source (or if you did not overlap the confinement volume or if you forgot to add a confinement volume).

The confine option is definitely not very efficient. I would recommend trying to get the same results you're trying to achieve without the use of confinement.

Marc

Dear all,
I'm trying to SPECT simulation.
But,  come the following message.
Please let me know if you know any clue.



*************************************************
LoopCount = 100000
Either the source distribution >> confinement
or any confining volume may not overlap with
the source distribution or any confining volumes
may not exist
If you have set confine then this will be igmored
for this event.

Thanks for your attentions.
