LS-DYNA’s ICFD solver is capable of successfully solving highly non linear FSI problems such as artificial heart valves and addressing its numerous challenges : strong pressure gradients, similar solid and fluid material densities, thin leaflets that undergo strong deformations, extensive mesh deformation and frequent remeshing, gap leakage treatment and so forth.

Blood flows through an artery 👇👇👇 The Carrreau non newtonian model has been chosen to model the blood. Windkessel type boundary conditions have been imposed on the different vessel outlets symbolizing the external blood load. When this boundary condition is used, the pressure will be imposed function of the total flux and some circuit parameters. In the electrical analog, pressure represents the scalar potential and flux the total current.

Dam break with Elastic gate The proposed test case consists of a flexible gate, clamped at one end and free at the other which interacts with a mass of water initially confined in a free surface tank behind the gate. Due to the uncertainty of the material used, an elastic material as well as hyperelastic models (Ogden, Mooney-Rivlin) will be tested.

In this LS-DYNA simulation shows a simple free surface example using the ICFD solver. A column of water collapses under the load of gravity. In order to set up such a problem, the domain must be divided in two ICFD_PART_VOLs, one for the fluid, one for the vacuum. For the automatic volume mesher to recognize the initial interface, the keyword MESH_INTERF must be used. Gravity load is applied through the use of LOAD_BODY keyword. Since the solver is implicit, no ramp up is needed.
