Objectives 1. Set up COMSOL for the FE implementation of the GWSh characterizing mechanical vibration of an L-shaped membrane. 2. Generate the first ten eigenvalues and eigenmodes for the base mesh. 3. Via a mesh refinement study, estimate the mesh necessary to predict the highest natural frequency to engineering accuracy. 4. Modify the membrane design by introducing a fillet in the concave corner and characterize the effect of fillet radius on the smallest and fourth vibration eigenmode.
