Execs Resign at Simulation Sciences

Less than two months after being acquired by British engineering group Siebe PLC, Simulation Sciences Inc. said Wednesday that two top executives have resigned.

The departing executives are Charles R. Harris, president and chief executive, and Robert E. Grice Jr., chief financial officer.

Siebe, one of Britain’s largest engineering and electronics firms, named industry veteran Lawrence M. Gozzard to succeed Harris as president of the Brea software supplier. The chief executive’s position was not mentioned.

At the time the deal was completed in April, Simulation Sciences said Harris would remain with the company but that his role hadn’t been defined.

Gozzard, who has more than 30 years’ experience in the software industry, was executive vice president of research and development at Simulation Sciences.

Grice’s responsibilities will be assumed by Ken Hastings, the company’s controller.

Simulation Sciences provides simulation software for the petroleum, petrochemical and industrial chemical process industries.
