Re: Two-groups diffusion equation - scattering from groups

Thanks a lot for debugging my input, Jaakko.
My first test shows B1_FISS zero for water, as expected.

Have a nice weekend,

Re: Two-groups diffusion equation - scattering from groups

Dear Jaakko, Thanks for your reply. Do you also get non-zero results for the last row in INF_FISS? Yes, I get similar values. INF_FISS = 0.001116 0.000850 0.024219 0.000590 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000902 0.001520 0.013487 0.001340 I'm attaching my in...

Two-groups diffusion equation - scattering from groups

Dear all, I'm using Serpent2 to generate coefficients and cross-sections to be used by a deterministic code solving the diffusion equation (two-groups). It runs fine but I'm puzzled by the scattering cross-sections from fast to thermal group. The wiki gives some directions, but I'm still unable to b...

Re: Multi-physics interface

Hello all,

I got rid of the error mentioned in my first post simply ignoring moderation from water. Despite not physically correct, I am trying to test the ifc interface at this moment.
I'll post again when/if I have useful information.

Sorry for the self-reply,

Vitor

Re: Multi-physics interface

Dear Jaakko, Could you please elaborate a little bit more on the "adaptive search mesh"? I'm sure I'm getting it wrong, but this is what I expected to happen when I pass an OpenFOAM mesh to Serpent: - Serpent gets the non-structured cells and use these cells to perform its calculations. This is poss...
