ANSYS was cleared by the FTC to acquire Fluent Inc. in a $300 million deal. Both companies sell Computational Fluid Dynamics (CFD) software, which is used to simulate the flow of liquids and gases. Many of the issues often confronted in software mergers were present in this deal. The acquisition will allow ANSYS to offer Fluent’s software with its own software suite to provide customers a broader array of products. EI economists William C. Myslinski, David D. Smith, and Robert A. Kneuper worked with lawyers at Goodwin & Proctor LLP to defend the acquisition.
