Re: Bugs in update 2.1.30

Hi,

Could you please share here (or send me in email) the link to version 2.1.30? The link which was distributed in February does not work for me.

Thanks,
Bálint

Re: Negative homogeneous surface flux

This is a 2D geometry. And i get negative homogeneous flux only in one assembly.
An other problem is, that the quotient of the heterogeneous and homogeneous flux is not exactly equal to the surface adf, and in some regions not even close to that.

Negative homogeneous surface flux

Dear All, I would like to get assembly discontinuity factor related data from the Serpent .res file. I use Serpent 2.1.27 and corrected the complex.c file. I have hexagonal geometry, and two energy group. I created a full VVER440 zone, and there is one assembly for which i get negative homogeneous s...

ADF surface numbers

Dear Jaakko! I'am trying to use Serpent ADF calculating option with version 2.1.26. I have some doubts about the numbering of the hexxc type surfaces. According to the description: http://serpent.vtt.fi/mediawiki/index.php/Output_parameters#Assembly_discontinuity_factors the numbering starts from ea...

Re: Group constant genration effect on k_eff

I don't do burnup calculations and i use the default optimalization options.

Re: Group constant genration effect on k_eff

Thanks for the answers. Yes i set a seed, the only differences in the inputs are the micro group srtuctures and the group constant generation setups. And i get that results.

Group constant genration effect on k_eff

Hi, I run almost the same script for generating group constatns in 9, 17 and 33 groups, but i had to change the built-in micro-group structure for the 17 and 33 group calculations. I had run the script without group constant generation too, and i also get different result. I use Serpent 2.1.24., par...

Re: Statistical test

Hi,

Thanks for your reply, i will try that.
I run the same script twice, only modifying parameters for group constant generation and i don't get the same keff within statistic error. I guess the problem is source convergence. Is there any way to test that?

Best wishes,

Statistical test

Hi, I'v read a paper about statistical tests in Sepent 2 ( http://montecarlo.vtt.fi/download/VTT-R-00371-14.pdf ), but is can't find how to use these options. It says "The statistical tests are performed automatically for the analog, implicit and collision estimates of kef.." but there is no “<input...
