Serving the Numerical Simulation community since 1989 
In 1987, the RASNA Corporation was founded in San Jose, CA and shortly thereafter began development of MECHANICA. Like predecessors FIESTA and PROBE, MECHANICA was based on the p-version of the FEM. This would become the fourth generation of FEA software.

“As the United States Air Force continues to extend the service life of their aircraft the Aircraft Structural Integrity Program (ASIP) has had to refine the methods it uses to analyze and predict fatigue crack growth. Through the use StressCheck, coupled with AFGROW, we in A-10 ASIP have been able to more accurately model, predict and analyze critical aircraft structure for the A-10 and other types of structure for non-A-10 system managers. This also allows us within the A-10 to more accurately assess risk for decision makers, streamline aircraft inductions into scheduled maintenance and reduce cost for total life cycle management.”
