Name That Fluid - Databases 201

AFT Software offers lots of different fluid modeling options of common fluids with the AFT Standard Fluids that are available in AFT Fathom, AFT Arrow, and AFT Impulse.  The AFT Standard Fluids can be accessed in the System Properties window and they provide fairly accurate thermophysical properties. But what happens when there is a fluid that you need to model and it does not exist as an AFT Standard Fluid in the software?  Well, there is no need to fret in this situation!  You can very easily create your own custom fluid and add it to the fluid database! The Fluid...

How Many Models of the Same System Do You Have?

Well, if the answer is "more than one", then you are probably struggling to deal with way more model files than you need to be.  With all AFT products, the Scenario Manager is an incredibly powerful feature that allows one to model several different cases within a single model file. This includes different operating conditions, multiple pump configurations, different piping, system expansions, hot days, cold days, insulation, fouling and pipe scaling, etc. The list of different cases that can be modeled is essentially endless! So, I have said it once, and I will say it again...The Scenario Manager is one of...

Using Groups

Groups of pipes and junction can be named for later recall. This is done using the Group Tools on the Edit menu. Groups may have subgroups, and pipes and junctions may be members of multiple groups. To create a group select the pipes and junctions you want in the group, then select Edit/Groups...Create. Specify a name for the group, click OK and the Group Manager will be displayed showing the pipes and junctions in the group. Group Manager can also be used to add or remove pipes and junctions from an existing group, rename a group or delete a group. After...

The Two P's: Why You Should Care That AFT is Celebrating Its 20th Year

There are two good reasons you should care that Applied Flow Technology is celebrating it's 20th anniversary this year.First is because 20 years in business means that AFT software is proven.Second is because of the prizes we are giving away this year. Twenty of them no less!Come along with me while I elaborate on what AFT has achieved in the last 20 years. And explain more about the two P's.A Vision for the VisualThe last 20 years has been a long and exciting journey. When AFT Fathom was released in April 1994, it was the world's first graphical software for pipe...

Using Duplicate Special to Easily Model Different Cases of an Single System

With AFT products, the Scenario Manager is an incredibly powerful feature that allows one to model several different cases in only one model file.  This includes different operating conditions, multiple pump configurations, different piping, system expansions, etc.  The list of different cases to model is essentially endless! Now, what if you have a single system and you would like to quickly model several cases where perhaps only a few parameters are changing?  You can start by building a single system on the Workspace.  Then you can use the “Duplicate Special” feature in the Edit menu to duplicate the entire system and...

Modeling Area Changes As Additional Pipe Fittings

If you have a system where there are several area changes throughout the piping, modeling every single area change and connecting pipes can become taxing and time consuming.  Also, the more pipes and junctions that are in a model, the higher the complexity. With AFT software, it is very simple to include the area change losses in the pipes themselves! As seen in the Pipe Fittings and Losses screen shot below, there are four area change types that can be used and either abrupt or conical shapes can be modeled.  The key to determining which expansion or contraction type to use...
