Now For Something Completely Different: The New Graph Guide in AFT Impulse 6

AFT Impulse will be celebrating it's 20th anniversary later this year in November. I was the original software developer of AFT Impulse back in 1996 and was still actively writing code up through AFT Impulse 4. So AFT Impulse is near and dear to my heart. Within the next few days we will be releasing AFT Impulse 6 and it will have some new and extremely powerful graphing features (more on that below).

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...

Don’t Be Negative! Be Positive!

Often times when building larger network models, you may not be sure what the direction of the flow will be and running the model is the only way to determine the flow direction. In the below AFT Arrow model it might be hard to determine what way the flow convention is in some of the loops. After running this model there are cautions stating that flow is negative through junctions that may have loss factors that are dependent upon direction. What is the easiest way to fix this? You could compare your results, remember or make a table of what pipes...

It would be more interesting if the program can define the flow direction itself, this way changing manually the input again and r... Read More

What Good is a Map Without Colors?

What Good is a Map Without Colors?
Each AFT software product employs five Primary Window tabs in which you would build, define, and analyze the model of your system.  Of these, the Visual Report window is incredibly useful in that you are able to overlay your model input or output parameters directly on top of the graphical layout of the system itself.  This is an excellent feature to use when you want to provide the bottom line results to clients and colleagues at a high level (or a detailed level).  Figure 1 is an example of what the Visual Report for a particular system might look like.  As...

Goodbye Graph Sets! Hello New Graph List Manager!!

Goodbye Graph Sets!  Hello New Graph List Manager!!
AFT software products have had powerful graphing capabilities for a very long time.  Many types of graphs can be created with AFT products such as pump vs. system curves, profile plots along a flow path, gradelines and elevation profiles, transient plots (with AFT Impulse or the AFT Fathom XTS module), slurry system curves (with AFT Fathom SSL or AFT Impulse SSL modules), and selected solutions that allow you to plot various output parameters for desired pipes. All of these graphing capabilities are incredibly important to engineers as they analyze the hydraulic behavior of their system.  The ability to customize the graphs...

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...
