About FEASTSMT                    
                   

FEAST (Finite Element Analysis of STructures) 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 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).

 

 

 

    

 

 

 

 

 
                   

Analysis Capabilities:

The latest version of FEAST caters to linear and nonlinear analysis capabilities. This is packaged in modular form for academic and commercial usage. It is capable of handling following analyses with metallic and composite material models.

Basic modules

  • Linear static
  • Free-vibration
  • Buckling
  • Visco-elasticity
  • Thermo-elasticity
  • Heat transfer
  • Contact analysis
  • Transient response
  • Frequency response
  • Random response
  • Shock response / spectra
  • Fluid-structure interaction
  • Base excitation

The software can be customised for specific user requirements. Inertia relief method for static analysis of unconstrained structures and Zernike Polynomial computation for assessing optical surface aberrations, are specific cases of customisation.
