Mallett experienced sustained growth over the next several decades, taking over the mid-Atlantic region and opening new offices in Philadelphia, Washington DC, and Research Triangle Park, North Carolina. Headquarters remained in Pittsburgh, Pennsylvania. Mallett was a premier source for ANSYS training and support and played a strong role in advancing the usage of FEA in the Eastern United States. Consulting remained a pillar of the product offering, often helping customers wade into the deep waters of new technology. Global adoption of ANSYS as the market-leading toolset was complete.
