Fig. 2From: Enhanced numerical integration scheme based on image-compression techniques: application to fictitious domain methodsA two-dimensional example of a discontinuous integral in the FCM, where the polynomial integrand \(\mathcal {P}(\xi ,\eta ) = 0.7 N_1 + 0.4 N_2 + 0.6 N_3 + 1 N_4 + 0.8 N_5 + 0.8 N_6 + 0.2 N_7 + 0.7 N_8 + 0.4 N_9\) is defined by a linear combination of the 3rd-order Lagrangian shape functions based on an equidistant nodal distributionBack to article page
