Fig. 4From: Large scale random fields generation using localized Karhunen–Loève expansionExample of parallel 2D random field generation steps. Gaussian 2D correlation function, with correlation lengths equal to \(l_{c1}=0.2L\) and \(l_{c2}=0.1\). KLE truncation error \(\epsilon ^2_{KL}=0.001\). Number of terms \(N=139\)Back to article page
