Negative KERMA xs

I previously ignored this from the code to calculate the energy deposition : lines 419-422: else Die(FUNCTION_NAME, "Mismatch in lowest energy of ACE and KERMA datas " "for nuclide %s (mt=%ld) \nACE: %.20E KERMA: %.20E", GetText(nuc + NUCLIDE_PTR_NAME), mt, E[0], E0[0]); lines 426-429: else Die(FUN...

Re: Fatal error in function ProcessPhotonProd

I got this error when I use KERMA data: Fatal error in function ReadPendfData: Mismatch in lowest energy of ACE and KERMA datas for nuclide 90232.03c (mt=3318) ACE: 9.99999999999999939497E-12 KERMA: 3.99441299999999960973E-03 and also many warning messages of negative xs points or negative non-fissi...

Re: Cuboidal Lattice (type 11) Syntax

my lattice was defined like this here:

lat 2 11 0.0 3.8545 0.0 9 6 1 8.1 7.709 1.0
38 39 38 46 28 65 52 73 7

Re: Cuboidal Lattice (type 11) Syntax

I tried the new version of serpent sss2.1.31 to my previous input file but with the new version I got this error: Input error in parameter "lat" on line 6724 in file "Input.i": Invalid value "11", must be between 1 and 9 Does the new version have different definition of the lattice type or any sugge...

Re: Calculation of heat distribution

Thank you Ville, that solved my problem. There is something I might haven't understood it which is the decay heat results after using rfw and then rfr. It seems that when I increase the power or time to create a binary file, the decay heat increases significantly. Well, that is reasonable but with m...

Re: Decay steps in automated burnup sequence

Hi, I also tried to run the example you provided in this link http://serpent.vtt.fi/mediawiki/index.php/Radioactive_decay_source,_practical_example and whenever I read the binary file I encounter this error: Processing electron data: - reading bremsstrahlung cross section data... - reading ground st...

Re: Calculation of heat distribution

Everything works perfectly. My issue now is how to get the decay heat from gamma using "dr -12" from the decay processes using the detector. It scored zeros when I wanted to get dr -12. Another thing is that my fuel has been already burnt and it has all the fission products, actinides ..etc. The que...

Re: Calculation of heat distribution

Hi serpent users, Thank you for your active participation which indeed is valuable for all users. As I am doing some heating calculation from light particles, mainly gamma, so if I used dr -4 I will get (b.eV) at a specific location. This (b.eV), as I understood, came from both n and p (if I used ph...
