Led to the development of an easy-to-use and interactive CFD software code for engineers. Ferit Boysan was one of the researchers who pioneered this technology at Sheffield University in the UK at the time. He partnered with Bart Patel, a department head at Creare Inc.

At the same time, Michael Engelman set up Fluid Dynamics International (FDI) in Chicago, Illinois, USA. FDI was a major player in finite element CFD. All three men became major driving forces in the growth of Fluent over the next 20 years.

This collaboration between Sheffield University and Creare Inc. Developed an interactive, easy-to-use CFD software product for the wider engineering community. Called FLUENT, the first version of this software was launched in October 1983. The term 'fluent' has its technological origin in the work of the brilliant 17th Century English physicist, Sir Isaac Newton, who used the phrase in one of his technical treatises on flow. When relating the word to flowing fluids he suggested its use for 'smooth' flows.

FLUENT was so successful and the CFD software business grew so rapidly that the Fluent group at Creare became a separate company, headquartered nearby in Lebanon, New Hampshire, in 1988. Quickly formed joint ventures in Europe and Japan, and over the next ten years, grew a network of corporate offices and distributorships serving all of the major industrialized nations of the world. In August 1995, Fluent Inc. Was acquired by Aavid Thermal Technologies, Inc., a Laconia, New Hampshire-based company, specializing in thermal management of electronic systems. This was followed by the first public offering of Aavid stock in the United States in January 1996. Rapid expansion of both Aavid's thermal management business and Fluent's software business ensued. In May 1996, Fluent acquired Fluid Dynamics International, the developer of the FIDAP software code and the nearest competitor in the CFD business.

This was followed in 1997 by the acquisition of Polyflow S.A., the developer of the POLYFLOW software code for CFD analysis of laminar viscoelastic flows. In January 2000, Aavid Thermal Technologies was purchased by Willis Stein & Partners, a private equity investment firm in the U.S. Since then we have continued to grow and maintain a strong position in the CFD marketplace. In May 2006, Fluent Inc.

Was acquired by ANSYS, Inc. (NASDAQ: ANSS), a Canonsburg, PA, computer-aided engineering (CAE) software company. ANSYS was formed in the early 1970’s and evolved out of a Structural/FEA modeling background, going public in the mid 1990’s on the NASDAQ. Both ANSYS and Fluent share a vision of /Simulation Driven Product Development/ within CAE software. ANSYS is committed to the continued advancement of its technologies to deliver breakthrough capabilities with tools and functionalities to perform tasks easier and faster than before without sacrificing accuracy or quality, and the ability to capture and share knowledge, all in an open, flexible, scalable CAE environment.

The information below was taken from the Fluent manual linked above. There is a lot of information about running Fluent in the manual so you should read all relevant portions before starting. Running FLUENT in Batch Mode FLUENT can be used interactively, with input from and display to your computer screen, or it can be used in a batch or background mode in which inputs are obtained from and outputs are stored in les.

Generally you will perform problem setup, initial calculations, and postprocessing of results in an interactive mode. However, when you are ready to perform a large number of iterative calculations, you may want to run FLUENT in batch or background mode. Copernic agent professional 6.12 key gen. This allows the computer resources to be prioritized, enables you to control the process from a le (eliminating the need for you to be present during the calculation), and also provides a record of the calculation history (residuals) in an output le. While the procedures for running FLUENT in a batch mode differ depending on your computer operating system Background Execution on Linux/UNIX Systems To run FLUENT in the background in a C-shell (csh) on a Linux/UNIX system, type a command of the following form at the system-level prompt: fluent 2d -g & outputfile & or in a Bourne/Korn-shell, type: fluent 2d -g outputfile 2&1 & In these examples.

fluent is the command you type to execute FLUENT interactively.g indicates that the program is to be run without the GUI or graphics. inputfile is a file of FLUENT commands that are identical to those that you would type interactively. outputfile is a file that the background job will create and which will contain the output that FLUENT would normally print to the screen (e.g., the menu prompts and residual reports). & tells the Linux/UNIX system to perform this task in background and to send all standard system errors (if any) to outputfile.

The file inputfile can be a journal file created in an earlier FLUENT session, or it can be a file that you have created using a text editor. In either case, the le must consist only of text interface commands (since the GUI is disabled during batch execution). A typical inputfile is shown below:; Read case file rc example.cas; Initialize the solution /solve/initialize/initialize-flow; Calculate 50 iterations it 50; Write data file wd example50.dat; Calculate another 50 iterations it 50; Write another data file wd example100.dat; Exit FLUENT exit yes This example file reads a case file example.cas, initializes the solution, and performs 100 iterations in two groups of 50, saving a new data le after each 50 iterations. The final line of the file terminates the session.

Note that the example input file makes use of the standard aliases for reading and writing case and data files and for iterating. (it is the alias for /solve/iterate, rc is the alias for /file/read-case, wd is the alias for /file/write-data, etc.) These predefined aliases allow you to execute commonly-used commands without entering the text menu in which they are found. In general, FLUENT assumes that input beginning with a / starts in the top-level text menu, so if you use any text commands for which aliases do not exist, you must be sure to type in the complete name of the command (e.g., /solve/initialize/initialize-flow). Note also that you can include comments in the le. As in the example above, comment lines must begin with a; (semicolon). An alternate strategy for submitting your batch run, as follows, has the advantage that the outputfile will contain a record of the commands in the inputfile. In this approach, you would submit the batch job in a C-shell using: fluent 2d -g -i inputfile & outputfile & or in a Bourne/Korn-shell using: fluent 2d -g -i inputfile outputfile 2&1 &.
