UITools is a powerful toolkit and a platform for building graphical user interfaces (GUI) for simulation programs, providing a wide range of solutions.

Pihldata has developed GUI's for simulation programs ranging from catalyzer, fuel consumption modelling, piston engines to gas turbine engines. As a solution to the common problems, UITools has been developed as a reusable platform.

Simulation programs are frequently developed in FORTRAN, C++ or Matlab, and may be difficult to use for others than the program developers, and may also be difficult to install. Using UITools as a platform for the GUI provides a powerful framework for a range of issues such as parametric input, result presentation, batch processing, on-line help system. The resulting GUI increases productivity and enables the users to analyze various aspects of the simulation programs.
