Clustered Energy Based Modal Assurance Criterion (CEMAC)

Implementation of the Clustered Energy Based Modal Assurance Criterion (CEMAC) based on the journal paper by Brehm et al. (2010)

The reference below proposes a mode pairing strategy using an enhanced modal assurance criterion based on modal strain energies. The procedure analyzed in section 3 (Mode assignment using energy-based modal assurance criterion) of this reference is programmed in this submission. This verification script verifies a specific result of section 4 (Benchmark study: cantilever truss), i.e. the fraction of the total modal strain energy of numerical eigenmode 1 that corresponds to vertical degrees of freedom, shown in Figure 7.
