Fig. 9From: Enhanced numerical integration scheme based on image-compression techniques: application to fictitious domain methodsExemplary cut cell (a) and the resulting sets of integration sub-cells when a QTD (b) or the IBR algorithm (c) are applied. Note that the local coordinate systems \(\varvec{\xi }\) are not depicted in the sub-figures for the sake of clarity.
