### Evaluation and Visualization Module

The user should first input the parameter * μ* = [

*μ*

_{1},

*μ*

_{2},

*μ*

_{3}] such that

*in [0.01, 0.5] × [2, 8] × [1, 10]. The user should also input a*

**μ***numerical parameter*that relates to the desired accuracy of the reduced basis output prediction

*N*

_{pr}in [1, 12],

*N*

_{du}in [1, 13]: the error in our prediction decreases as

*N*increases.

The code then displays, for the
desired parameter value * μ* = [

*μ*

_{1},

*μ*

_{2},

*μ*

_{3}], (

*i*) the contour of the field, and (

*ii*) the value of the output/quantity of interest. In each case, we also provide a certificate of fidelity that rigorously bounds the error in our reduced basis prediction relative to the highly accurate (and hence very expensive) "truth'' Finite Element solution.
