Fig. 15From: Enhanced numerical integration scheme based on image-compression techniques: application to fictitious domain methodsCombination of the RFIP approach with the IBR method (IBR\(^{*}\)). This example is based on the compressed set of sub-cells \(\varvec{\mathcal {R}}\) depicted in Fig. 12b where a 4 \(\times \) 4-point Gaussian quadrature rule is assumedBack to article page
