Computational Fluid Dynamics using GAMBIT and FLUENT

FLUENT is now located on our PC platforms and operates as any other program does under Windows. You can start it by using the 'Start' logo and go to 'Programs.' You will find the FLUENT folder listed. Gambit is a Windows based program for the generation of the geometry and grid systems need in the computations done by FLUENT.

There will be new assignments associated with the FLUENT problem. First, there are several tutorial sessions you must work through using Gambit. There will be a one page or less report associated with your evaluation of the Gambit tutorials. This must be turned in; however, it will not be graded, but will be sent to FLUENT, with your permission. It is expected that you will work with others to learn Gambit and FLUENT. Your FLUENT grade will be based on your problem development and solution report. This report must be totally independent of any other student's work. The development of the geometry and grid system has become one of the most important steps in computational fluid dynamics.

After learning Gambit, you need to select a geometry that you are going to use for your individual problem. To help you in this process, a number of example problems have been brought together with a set of further instructions. You may use any two-dimensional geometry you want. You are not restricted to the suggestions. You will need to turn in your selection as soon as possible so that we can avoid duplication between efforts. There are a number of suggestions for your FLUENT problem.

After selecting a geometry, you need to develop the geometry and the grid system before using FLUENT to calculate the flow, just as was done in the tutorials. You may have some system problems in using Gambit as this is the first year we are using it and there has been some problems in connectivity with the server. However, once you have generated the geometry and gird, they must be saved. These can be read into FLUENT 4.5, that is to be used for structured grids calculations; i.e., orthogonal systems. FLUENT 5.2 is needed for unstructured grids, which can be used for more complex geometries.

It would be a good idea to look at FLUENT's Home Page to see examples and other ideas. The final FLUENT report will be due the Monday of the last week of class. It will not be accepted beyond this date. You should establish your problem yourself by the end of the coverage of Chapter 7 (about the 4th week).
