FEAST^SMT (Finite Element Analysis of Structures-Substructured and Multithreaded) is the structural and heat transfer analysis software based on finite element method realized by Vikram Sarabhai Space Centre / Indian Space Research Organisation. It is supported by state-of-the-art pre/post processor - PreWin. Sub-structured and multi-threaded implementation of the solver ensures high performance by exploiting multi-core architecture of modern computing platforms.

The software has Static, Free-vibration, Buckling, Transient, Frequency, Random response and Heat transfer capabilities. These capabilities are supported by a rich element library comprising beam, shell, solid, axisymmetric, spring, rigid-links, gap etc. and can handle isotropic, orthotropic, laminate composites and viscoelastic material models. The above features enable real-life applications of FEAST^SMT in structural engineering, solid mechanics and heat transfer problems of Aerospace, Automobile, Civil, Mechanical and Marine engineering. The cost of owning the software is competitive in comparison with similar non-indigenous software packages. The software can be deployed in Linux and Windows operating systems with minimum hardware requirements. It is available in three versions. The classification is based on number of finite element nodes viz; Academic (for students and educational institutions), Premium (for small and medium scale industries) and Professional (for general large scale applications).
