# Optimization Using Radioss

In this tutorial, you will learn how to perform an optimization using the Design Explorer workflow.

The model used for the optimization is a B-Pillar cut from a full car model. An initial velocity is applied to a rigid cylinder in the transverse (Y) direction.

The objective of the optimization is to minimize the mass of the B-Pillar while constraining the maximum displacement of a node on the inner panel to less than 19.7 mm.
