Chemical potential field \( {\hat{\mu }} = \mu /\mu _{\max } \) in the microscopic domain at time step \( {\hat{t}} = 250\Delta {\hat{t}} \). a Fully resolved finite element solution \( {\hat{\mu }}^{FE} \)b reduced order solution \( {\hat{\mu }}^{ROM} \) and c the relative error with respect to their average \( \frac{{\hat{\mu }}^{FE}-{\hat{\mu }}^{ROM}}{0.5({\hat{\mu }}^{FE}+{\hat{\mu }}^{ROM})} \)
