An Eulerian method for fluid-structure interaction with biophysical applications

International audienceAn eulerian approach for fluid-structure coupling is presented for generic fluid-structure coupling an elastic body with an incompressible fluid. Fluid-solid interfaces are captured by a level-set method. The main features of the method are its simplicity, and its natural control of mass and energy. We are indeed able to prove an energy equation which ensures in particular that the regularization of the force does not involve any energy dissipation. Applications to membranes oscillation and cardiomyocyte contraction are presented
