Backup Files

All AFT Products automatically generate backup files each time you save your model. Backup files will be saved to the same location you have saved your model file to. They will have the exact file name as your model, but rather than having the extension *.fth, *.aro, *.imp, etc., they will have the extension *.001, *.002, *.003, etc. Every time you click save while working in your model, a new backup file will be created. If the maximum number of backup files already exists, the new backup file will overwrite the oldest backup file. The maximum number of backup files created...

The Quickest Way to Learn AFT Products

After you receive your AFT software, you will probably wonder how to learn the software quickly so you can begin using it.  AFT provides a very handy Quick Start Guide for each software product in English Units and SI Units.  These quick start guides are short, concise, would take maybe a day of your time, and are extremely powerful to assist you in producing highly accurate and advanced models! With larger companies, sometimes the AFT software will go straight to the IT department for installation and the engineer may never see the hard copy of the quick start guides.  Not to...

How to Fill as Quadratic

Filters and screens impose a pressure drop that varies with flow rate. The variation is non-linear, but manufacturers will often provide only one data point for pressure loss at the design flow rate. Using a single point, or constant pressure drop, can produce significant inaccuracies in your model. With this in mind, AFT offers the “Fill As Quadratic” option for entering loss data.   Using only a single point, “Fill As Quadratic” will create two additional points for you. This first is simply 0,0; zero flow produces zero pressure drop. The second point is 2 x Flow and 4 x Pressure...

Printing Input and Output

You can print all of or select portions of your model data window in order to have a hard copy of your input. Likewise you can print all of or select portions of your output window in order to have a hardcopy of the output. Printing both of these windows allows you to have hardcopies and backups of everything you would need to perform calculation checks on your model. After building your model and entering all of the required data, browse to the Model Data window and click “View/Model Data Control”. After setting up the input data to be displayed, click...
