Fluid-Structure Interaction
The Fluid-Structure Interaction interface can be used to compute the flow of a liquid or gas around a moving microstructure. A typical application is the simulation of microvalves. The physics interface can be used to model both turbulent and laminar flows at low Mach numbers.
The Fluid-Structure Interaction interface uses the arbitrary Lagrangian-Eulerian (ALE) method to combine the fluid flow equations, formulated using an Eulerian description and a spatial frame, with the solid mechanics equations, formulated using a Lagrangian description and a material (reference) frame. The Fluid-Structure Interaction couplings appear on the boundaries between the fluid and the solid.
