Simulating Beam Deformation Using FSI in CONVERGE

In CONVERGE 3.0, you can quickly set up and simulate beam deformation caused by fluid-structure interaction (FSI). While a specific user-defined function was required to simulate a 1D bending beam in version 2.4, the same case can be set up in a matter of minutes directly in CONVERGE Studio in version 3.0. CONVERGE 3.0 incorporates a special beam FSI object that solves a simplified 1D finite element problem as part of a coupled FSI analysis. In the video, the top view shows pressure, and the bottom view shows velocity, with blue indicating low and red indicating high in both instances. In the top view, you can see how the beam bends as pressure is increased on the left-hand side. The bottom view demonstrates how Adaptive Mesh Refinement was leveraged to capture gradients in velocity. This method can be applied to quickly and accurately simulate objects such as reed valves.

Convergent Science's CONVERGE is an innovative computational fluid dynamics (CFD) software that eliminates the grid generation bottleneck from the simulation process through autonomous meshing.
