PolyDyna
An educational MATLAB code for topology optimization of structures subjected to dynamic loads.
PolyDyna uses the HHT-α method to solve the structural dynamics problem and uses the differentiate-then-integrate method for sensitivity analysis. The code can handle general dynamic loads which can change in magnitude, direction, or position over time.
