Fig. 4From: Effect of the separated approximation of input data in the accuracy of the resulting PGD solutionSpatial distribution of errors (\(\Vert k^\text {sep} - k\Vert \)) of the separated k function including 30 terms. Errors are computed at nodal points of a \(100\times 100\) uniform structured mesh. When compared with k (Fig. 5), errors are a highly oscillatory, small amplitude functionBack to article page
