Calculation of Flux Harmonics and Higher Eigenvalues

Hi OpenMC community,

I am looking for methods to calculate higher eigenvalues and eigenmodes using OpenMC. I know Serpent has fission matrix capability, and MCNP seems to it have too in its R&D version. Any suggestions or useful reference on this subject matter?

Thank you very much.

Sorry this never got a response – the main version of OpenMC does not have a capability for computing the fission matrix at present. There have been a few research efforts / branches where such a capability was added, but it never made it back to the main branch of the code.
