• SciComp is a developer of automatic software synthesis tools. Our current focus is on complex applications involving mathematical modeling. We provide tools that enable users to generate scientific computing codes without the laborious and error-prone manual programming process. Designers need only describe the equations they are trying to solve, the variables over which they want to see solutions, and the interfaces to inputs (e.g., meshing routines), outputs (e.g., visualization packages) and data analysis components. Our products then produce codes in languages such as Fortran, C or Fortran90 that are optimized for the specific application and target machines.
