Project790 is a pure Fortran(KISS) Object Oriented Framework for the solution of Finite Element Method based problems. This framework serves three distinct purposes:

• For students and engineers interested in making use of the different applications already developed:
  • Thermal2D Solves Poisson's equation with Dirichlet and Neumann conditions for steady heat transfer problems in two-dimensional domains. Presents as results:
    • Temperature distribution
    • Heat flux distribution
  • Thermal2DTransient Same as the above application but for unsteady problems, presenting solutions for all time steps.
  • Thermal3D Same as Thermal2D but for three-dimensional domains.
  • Structural2D Solves the linear elasticity equations for solids under the hypothesis of plane stress or plane strain. Presents as results:
    • Displacement field
    • Normal and shear stress field
    • Strain distribution
  • Structural3D Solves the linear elasticity equations for three-dimensional solids. Presents the same results as the above application.
  • ThermalStructural2D Solves in tandem the heat transfer equation and the linear elasticity equation for two-dimensional problems. To the structural calculation it is added an initial deformacion for a temperature differential Δt.
  • CFD2D Solves Euler's equations for two-dimensional domains and compressible flow. Presents as results:
    • Velocity field
    • Pressure distribution
    • Temperature distribution
    • Mach distribution
    • Internal Energy distribution
    • Density distribution
• For people interested in making use of the Framework's features in order to develop their own applications. To whom, a wiki will be available soon. Altough we hope that looking at the currently existing applications serves as a clear enough guide to obtain the general ideas.
• For developers and students interested in getting into the framework's core classes, be it in order to add new features, or to borrow some ideas for their own developments!
