GEFGAP

GEFGAP, which stands for General Engineering Fluid Dynamics Analysis Program, is a software package developed for simulating fluid flow and heat transfer phenomena. It is used across various engineering disciplines, including aerospace, automotive, and mechanical engineering. The software employs computational fluid dynamics (CFD) methods to solve the governing equations of fluid motion and energy transport.

GEFGAP allows users to create complex geometric models of their designs and then define fluid properties and boundary conditions. It discretizes these models into a mesh of smaller cells, over which it iteratively solves the equations. The output of GEFGAP simulations includes detailed information about velocity fields, pressure distributions, temperature gradients, and other relevant flow characteristics. This data is invaluable for engineers seeking to optimize designs, predict performance, and identify potential issues before physical prototyping.

The capabilities of GEFGAP extend to a wide range of flow regimes, from laminar to turbulent, and can handle both compressible and incompressible flows. It also supports various turbulence models and numerical schemes, offering flexibility in problem setup and solution accuracy. Visualization tools within GEFGAP enable users to interpret simulation results effectively, often presented as contour plots, vector fields, and animations. Its application aids in understanding phenomena such as aerodynamic lift and drag, internal cooling, and combustion processes.
