SOFC, thermal wave

Thermal instability may cause convergence problems in numerical steady-state SOFC models, which include thermal effects. Roundoff errors in numerical calculations may occasionally take the form of long-wave perturbation this initially negligible disturbance would then grow exponentially during the iteration process and it may destroy the convergence of the numerical scheme.
