Sensitivity Analysis of a Communication Mast Detail

Application ID: 4737

The example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. A senior design engineer can sometimes reach acceptable performance after analyzing only a handful of designs, while an unexperienced analyst may have to spend a lot of time on failed attempts.

Usually, you can indeed improve a design by trial and error, but it is difficult to ensure that the price you pay—in this example, added weight and material costs—is as low as possible. With sensitivity analysis, you can find the most cost-efficient direction for a small modification and estimate the effect it will have before attempting an updated design.
