ANSYS makes engineering simulation software that companies can use early on in the development process to predict how well a design might function and behave in the real world. Engineers and designers in a wide array of industries -- including automotive, aerospace, biomedical, defense, and electronics -- use its products to help minimize costs and reduce the amount of time it takes to rollout a finished product.

Over the course of nearly 40 years, the company has built a loyal client base. About three quarters of its revenue is from repeat customers. Steven M. Ashley, an analyst at Robert W. Baird, says that the simulation software market could see double-digit growth for years to come, which could mean that ANSYS will continue to please investors.
