Finite Element Modeling Continuous Improvement (FEMCI)

Advancing Spacecraft Reliability Through Shared Analysis Methods
Finite Element Modeling Continuous Improvement (FEMCI) is an online archive of mostly NASTRAN (NASA STRuctural ANalysis) based finite element analysis information. Some information can be applied to other finite element analysis programs, such as the principles behind the validity checks, but in general, FEMCI is exclusively NASTRAN. “NASTRAN-based” refers to software or tools that utilize the core capabilities of the NASTRAN finite element analysis (FEA) solver, which was originally developed by NASA for structural analysis. NASTRAN was originally developed for NASA in the late 1960s as a generic finite element analysis program, and is still commonly used today for complex numerical modeling of physical systems in a wide variety of engineering disciplines.
The FEMCI Book is an online FEM and structural analysis resource geared toward the needs of the aerospace community. Originally established in 1994, FEMCI serves as a mechanism to distribute information on the finite element analysis (FEA) and structural analysis techniques necessary for a complete and accurate structural analysis of spacecraft and spacecraft components. The FEMCI Book contains descriptions of various analytical tools and techniques, ranging from computer intensive dynamics and kinematic analyses to detailed hand stress analysis.
FEMCI is a dynamic tool, meant to grow with the needs of its community. It acts as a central location for knowledge capture of FEA and other analytical techniques and attempts to encourage the distribution of that information with the overall goal of improving the accuracy and efficiency of structural analysis at Goddard Space Flight Center.
FEMCI stands as a globally recognized resource for structural analysis that has been utilized by analysts worldwide for over two decades. What makes FEMCI truly unique is its comprehensive compilation of structural analysis best practices and techniques, which significantly enhances the quality of designs and success rates for both commercial and NASA projects. Goddard’s ETD FEMCI analysts are uniquely positioned as the authority in this specialized field due to the extensive knowledge and experience it’s analysts have accumulated while solving complex engineering challenges for cutting-edge science missions. As the only organization that has consistently provided this resource for more than 20 years, ETD rightfully maintains its reputation as the expert community that others turn to when facing difficult structural problems. Through FEMCI, we continue to establish NASA’s leadership in critical areas such as NASA structural analysis, random vibration, and finite element analysis, serving as an invaluable public resource for the global engineering community.
