Fig. 10From: Enhanced numerical integration scheme based on image-compression techniques: application to fictitious domain methodsQTD of a cut cell and corresponding pixel-image. The pixel values 0, 1 and 2 denote physical, fictitious and cut sub-cells, respectively. The image consist of \(2^k \times 2^k\) pixels, where k is the refinement level of the QTD (\(k=5\))Back to article page
