Accuracy of the MEG-IsoQuad Method and geometric parametric analysis. a B-Rep to reduced order model evaluation accuracy analysis on the T-shape part. Used set of parameters is \(P^{acc}_{T-shape} = \lbrace X1=40, Y1=40, Z1=35, X2=40, Y2=40,Z2=35, X3=40, Y3=40, Z3=35 \rbrace \). Triangulated mesh (depicted in blue) and generated 3D quadrilateral mesh (depicted in gray), geometric difference is almost zero (left). Geometric comparison between the reduced order model evaluation and a validation snapshot for the same set of parameters \(P^{acc}_{T-shape}\) (middle). Distance error analysis of (a, middle) mapped onto the reduced order evaluation (right). b Reduced order model truncated basis influence on the casting part. Used snapshot has parameters \(P^{acc}_{Casting}= \lbrace L=80, Rb=120, Rh=35, Ri=20, Hb=15, Hh=140 \rbrace \). Distance error is analyzed between the reduced order model evaluation and the corresponding snapshot and mapped on the reduced order model evaluation. Error with a basis constructed from the first 5 modes (left). Error using 15 modes (middle). Error using 25 modes (right)
