Re: trans S s1 0 0 0 0.0 0.0 0.0000001 2 mirrors!

I re-tested with an unmodified version of 2.1.32 and I don't see the issue any more. Thank you for the help!

Keeping interfaces constant is a virtue as well :-)

And now since it is "documented" to stay the way it is, I can work around it in e.g. SerpentTools.

Thank you for the clarification.

Best regards,

How serpentTools processes Serpent outputs, probably is a question for serpentTools team. Yes, however, that is not the question. I'm discussing the interface serpent has to any post-processing system one wishes to use. SerpentTools was just an example. Regardless of the post-processing system used...

Yes, I can see Serpent saves the grid as it does. The question is rather: should it ?

For example, it confuses SerpentTools: The R,Z plot it creates is vertically displaced.

Hi! Maybe this is a feature instead of a bug, but it sure is confusing: When using a Cylindrical mesh for detector, like this: det myDet1 n dtl mySurf1 dn 1 440 645 20 0.0 72.0 36 -114 114 23 The output has the z-slots in "reverse order": (The following is through SerpentTools, but the same thing is...

Re: Serpent UGM 2020

Hi!

IMHO, the Corona situation is still quite likely to force the cancellation of the face-to-face meeting.

What is the backup-plan?

(Perhaps: postponing, virtualization)

Thank you very much!

Thank you for the further testing and the colourful pictures.

Do I interpret your message correctly: "You confirm that you can recreate the bug."?

Cheerio!

Geometry limits...source and significance

Hi! The general interest questions are these: 1) How does Serpent decide the geometry limits? 2) Where are they used in? Especially, do they affect the neutron transport calculation? (I noticed them being used with -checkvolumes.) Here is the background issue: I have an MCNP model converted to Serpe...

Re: Flux detector output confusion

However, varying the source energy I noticed that for say MeV neutrons the outputs of the detectors are the same. For 0.025 eV, the aluminum ones (dm and dtl) don't change but the He3 output for both dm and dtl is lower. It seems to me that since He3 is a strong thermal neutron absorber, the histor...
