Fig. 6From: Effect of the separated approximation of input data in the accuracy of the resulting PGD solutionEvolution of the error of the PGD solution with the number of terms for a \(k^\text {sep}\) function with discretized on the nodes. The separated diffusivity function is discretized on a grid that coincides with the nodal points used to describe the solution \(u^\text {sep}\) Back to article page
