Siemens PLM named Robert R. Ryan CEO of its CD-adapco subsidiary, whose president, CEO and cofounder, Steve MacDonald, passed away a few months before its acquisition by Siemens early this year. Ryan’s appointment puts a seasoned, world-class CAE executive at the helm of Siemens PLM’s CFD business. Ryan’s previous positions include chairman and CEO of ADAMS developer Mechanical Dynamics, Inc., acquired by MSC Software in 2002. Ryan’s appointment also strengthens confidence that the HEEDS multidisciplinary design exploration software from Red Cedar Technology—a CD-adapco subsidiary of which Ryan was CEO, and which Siemens PLM acquired in its CD-adapco purchase—will continue to receive proper resources, attention and management support.
