Calculation of higher eigen-modes of the forward and adjoint neutron diffusion equations using IRAM algorithm based on domain decomposition
• Higher forward and adjoint eigen-modes are computed for neutron diffusion equations. • IRAM and PGMRES from open source packages SLEPc and PETSc are employed along with domain decomposition. • Theoretical analysis of higher eigen-modes and degeneracy are performed. • IAEA-3D, PHWR and an analytica...

Calculation of higher eigen-modes of the forward and adjoint neutron diffusion equations using IRAM algorithm based on domain decomposition |
| abstract |
• Higher forward and adjoint eigen-modes are computed for neutron diffusion equations. • IRAM and PGMRES from open source packages SLEPc and PETSc are employed along with domain decomposition. • Theoretical analysis of higher eigen-modes and degeneracy are performed. • IAEA-3D, PHWR and an analytical cubic problem are solved for verification. • Numerical results agree well with the anticipated theoretical analysis. |
