CFD Studio

Introduction
     
  Modeling and Simulating Fluid Flow and Heat Transfer Problems
   

CFD Studio is a software that allows the numerical simulation of 2D fluid flow and heat transfer problems. It was developed for educational purposes and can be used in heat transfer (conduction and convection) and CFD courses.

Main features:

•  Finite-volume approach;
•  Fully-implicit formulation
•  Troubleshooting exclusevely elliptics;
•  Boundary-fitted coordinates, which allows arbitrary domains to be used;
•  Segregated solution of the equation set using the SIMPLE and SIMPLEC methods;
•  Coupled conduction-convection problems
•  CDS, UDS and WUDS interpolation functions
•  Using fictitious volumes for applying boundary conditions
•  Co-located arrangement 
•  Linear system solver using Jacobi, Gauss-Seidel and TDMA

Technical features:
      
          1)     work-pad – Fig. 2: 

          •      Visualization of the numerical problem and its parameters(Figure 3);  
          •      File export of the problem data in independent XML of operating system;  
          •      Total control on the software and its elements: pre-processor, processor and Post-processor.

         2)    Pre-processor

         •     2D mesh generator and editor fully interactive through the mouse – figure 4;
         •     Geometries can be imported from another software; 
         •     Direct coupling between the mesh editor, viewer 3D and the interface controls/parameters; 
         •     Fully graphical input parameters through the 2D editor(fields scalars/vectors, boundary conditions,   equations parameters, etc);

        3)     Processor – Figure 5

        •      Transient results can be viewed interactively; 
        •      Export of the transients and/or-steady state results in a proprietary format;

        4)    Post-processor

        •      3D Viewer for the visualization of the results– Figure 6;
        •      Iso-lines, iso-surfaces, scalars and vector fields;  
        •      Interface customization (colors, preferences, etc); 
        •      Export of the results in a proprietary format;  
        •      Export of the solution images in the TIFF and BMP formats.
