You can use GAMBIT 2.4.6 to build its geometry and create a mesh for it or to enter the geometry created by other CAD / CAE software and make changes and produce mesh on it. The Fluent software is a CFD numerical calculator with the theory of fluid theory, in fact, the combination of the theory of fluid science and the numerical computations of the Computational Fluid Dynamics method in Fluent.

Method: The Computational Fluid Dynamics (CFD) simulation of the cross-flow membrane is done by using ANSYS Fluent 6.3. The meshing of the geometry of the membrane is done by Gambit 2.4.6 and a grid size of 100674, the number of faces is 151651 and number of nodes being 50978 has been selected for the simulation purpose from the grid independence test. We have revised and included all patents in the manuscripts related to the membrane filtration unit.
Abstract This research paper aims to study the effect of attaching a Gurney flap on the trailing edge of an inverted NACA 23012 rear wing. The model was created in AutoCAD 2013, and the mesh was defined in the pre-processing software ANSYS Gambit 2.4.6. The flow analyses were done considering the rear wing to be placed in a pressure far field without considering the ground effect. The results were plotted for various factors like downforce, drag and the downforce to drag (L/D) ratio for various heights of the Gurney flap. A velocity inlet model for an air speed of 0.1 Mach (33 m/s) was chosen and the analyses were iterated with different angles of attack. The standard two- equation turbulence kinetic energy and turbulence dissipation model was chosen for the solver. The numerical analysis was carried out in ANSYS Fluent 14.5. The contours of pressure distribution, pressure coefficient and the flow path lines generated were visualized for varying flow characteristics within the computational domain. It was observed that the downforce to drag (L/D) ratio increases with an increase in the angle of attack and the Gurney height.
The drawing file was imported into ANSYS Gambit 2.4.6 and the meshes were created such that they conform to the mapping, i.e., at any given point along the surface of the profile, the mesh lines are perpendicular. During initial meshing, several lines were skewed and on refining the mesh, it was rectified and the desired mesh was obtained. The rectangular blocks were created around the rear wing. 2ff7e9595c
