Description  Back to Top

A two-dimensional, finite element model for simulating coupled multiphase flow and multi-component transport in planar or radically symmetric vertical sections. MOFAT evaluates flow and transport for water, nonaqueous phase liquid (NAPL), and gas. The program also can be used when gas and/or NAPL phases are absent in part or all of the domain. The flow module can analyze either two-phase flow of water and NAPL in a system of constant gas pressure or explicit three-phase flow of water. The transport module can accommodate up to five components partitioning among water, NAPL, gas, and solid phases, assuming either local equilibrium interphase mass transfer or first-order kinetically controlled mass transfer.

Minimum System Requirements  Back to Top

This system was designed to run under DOS (Disk Operating System) on an IBM PC, XT, AT, PS2, or compatible computer. Graphics capability is not required, but is highly recommended, as most programs will produce graphics output. Graphics support is provided for the Hercules graphics card, the Color Graphics Adapter (CGA), and the Enhanced Graphics Adapter (EGA). At least 512 kilobytes (Kb) of random access memory (RAM) is required, but 640 Kb is recommended. An arithmetic co-processor chip is strongly recommended due to the computationally intensive nature of the programs, but is not required for use. Programs may be run from floppy diskette, however, a fixed disk is required to use the programs from the system menu. The system storage requirement is approximately three megabytes.

Installation and Start-Up  Back to Top

Getting Started:

You will need unzipping (compression) software to uncompress ZIP files. If you need to load compression software on your computer, free software is available for download on the internet at the following sites:

http://www.pkunzip.com -  PKUNZIP home page
http://www.cdrom.com/pub/infozip - InfoZip Wiz

You will need Adobe Acrobat Reader to view the documentation (PDF) files. The Reader is available free from Adobe at the sites below:

http://www.adobe.com - Adobe Reader download page
ftp://ftp.adobe.com - Adobe anonymous ftp home page

Installing the Program:

Two files are available for download:

• mofat.zip (362 Kb): Program and installation files
• mofat.pdf (2,800 Kb): User's Manual

1. View or download the User’s Manual (mofat.pdf) file for further installation instructions.
2. Go to Windows Explorer and create a directory (folder) named MOFAT.
3. Download MOFAT.ZIP to the new MOFAT directory.
4. From the MOFAT directory you created, run MOFAT.ZIP by double clicking on the file (compression software required).
5. Unzip the files to the same MOFAT directory.
6. Download and review the Users Manual (MOFAT.PDF) for instruction on running the model.
7. Before running the MOFAT2.EXE program, a file must be copied at the DOS prompt as described below.
   
   If your computer's RAM size is equal to or greater than 4 MB and less than 8 MB, then : COPY 4MBRAM.BLK MOFAT.BLK
   
   If your computer's RAM size is equal to or greater than 8 MB, then : COPY 8MBRAM.BLK MOFAT.BLK
   
   
8. Start the MOFAT program by double clicking on the MOFAT2.EXE file.
