Desenvolvimento de uma interface gráfica para o solver fluids 3D de dinâmica dos fluidos computacional

Abstract

The Laboratory of Heat Transfer and Mass and Fluid Dynamics of the LTMC / FEMEC / UFU has been developing several works for simulations and computational analysis of fluid dynamics, however with stages provided by software proprietors, turning onerous the use of such solutions. Besides, the functional tool existent, that it makes such simulations, it was developed in the Fortran language, without a graphic interface, don t allowing a previous visualization of the geometries, what hinders the handling of the same. In that way, in this work a methodology for the construction of geometries and the generation of their triangular meshes of superficial finite elements, being used of free software, for subsequent import in an program dedicated to the computational analysis of fluid dynamics, through the immersed boundery method. Among the tools analyzed for the modeling and generation of the geometry and their mesh, was opted for the use of GMSH, for being free software, for being an executable program in Linux and Windows platforms, intuitive and of easy learning. Among the tools analyzed for the development of the graphical interface, was opted for PHP, for being a language script of open source of general use, very used, and especially provided for the development of applications Web inside of codes source of language HTML. As every code generated in PHP is "embedded" in the code HTML, the WEB server is responsible for to interpret the code and to transform it in the interface that will be seen by the users. Using this language, the connection with the LTCM server is made in a fast way and without complications, through the WEB. The work will present some solutions of geometries / meshes generated in GMSH, and the preparation of those solutions for the use of the immersed boundary method in the computational analysis of fluid dynamics of geometries as spheres, cylinders, trying to uses software to work with more complex forms as aircrafts and automobiles.
