Dissipative Coupling of Fluid and Immersed Objects for Modelling of Cells in Flow

<div>Constricted flow between two cylindrical obstacles. On top, the flow of cell with correct value of friction parameter 1.56 is depicted. Below, overlay of two simulations is shown: simulation with correct value of friction 1.56 (cell cross section with thin line) and simulation with lower value of friction 0.8 (cell cross section with thick line). Snapshots are depicted at time instances <span class="nowrap"><svg height="9.92533pt" id="M151" style="vertical-align:-1.57651pt" version="1.1" viewbox="-0.0498162 -8.34882 84.551 9.92533"
