Reflector ADF calculation in 2.1.22 and 2.1.23

Hello, I wrote a simplified core strip mode to calculate the cross section and ADF in the core reflector so that I can use it for diffusion code. However I have come across some trouble in using different version serpent doing the calculation. I use the same command in form of set adf reflector_uni ...

Re: pin power map

Hi,

Not really, as one pin is missing, I have only got 263 pins' power in a LWR lattice, here I attached the input and output, could you help me to check the reason?

Thank you very much.

Re: pin power map

Hello,

I have come across the same problem, have you find an answer for this? The case is, if I use same assembly in the array, the result is alright, however, if there were more than one array, the pin with index 1 will miss in some assembles. Does anybody came cross this before?

Thanks!

Re: 3D lat example request

Sorry, for the segmentation fault I discussed with the IT administrator who in charge of compiling serpent. She told me she have to do a special version for me to enable debugging option and may cost lot of work and time, and also may bring trouble to other users of institute. Thus she suggested me ...

Re: 3D lat example request

I run the same input with 2.1.20 ompi , 2.1.20 and 2.1.18 respectively, I think it is due to the new version as I got the expected output power density in 2.1.18 but in 2.1.20 the output power density is much larger, I did not got the reason why. Here is the output in 2.1.18, ran without ompi, TOT_P...

Re: 3D lat example request

By the way, I also kept coming across "Segmentation fault" while running lat 11, what may the reason be? The version is 2.1.20. Also another question is about the power density, in the input I set the powdens 26E-9, when I use ompi doing the calculation, with 10 nodes, the printed output of first st...
