Trying to simulate a simple 2-way FSI: fluid flow over a beam with a low modulus (1e4 Pa) based on the oscillating plate tutorial geometry. Changing the mesh and transient properties has helped to a degree but the highly distorted element error persists. The error reports that the structural component is at fault, but the animation (attached) shows Fluent's mesh distorting. It is likely not showing the structural distortion.
Any help would be appreciated. Attached are the workbench files, animation, and photo demonstrating the distortion.
Mesh and time steps were reduced for file size.
