How to use AFT Workspace Layers

We are excited to share Workspace Layers, a new feature for the Applied Flow Technology software suite that you'll be working with soon! A group of layers is like a stack of transparencies. Each layer displays specific, customizable information and together they combine to form the Workspace view for your model. This is concept is much like Adobe P...

Quickly Renumber Your Pipes and Junctions

When building a model in any of AFT's software all pipe and junction numbers must be unique. These pipe and junction numbers can be useful for sorting information in areas such as "Model Data" and "Output". Therefore, keeping an organized structure for these pipe and junction numbers is strongly advised. Though, like every project, unforeseen devel...

Declutter Your Natural Gas Model

I don't have any tips for decluttering your garage or office desk, but I can offer you a tip on how to declutter your natural gas model. Perhaps it will save you some time as well in the design phase. As engineers, we like details and will enter as many as possible into our models. I've seen several AFT Arrow and xStream models with natural gas mix...

Using Cost Libraries for Optimal Engineering

This blog assumes users already know how to import engineering and cost libraries into the software. If you do not, we recommend checking out this example problem from the help file. One of the lesser-known features of AFT products is the ability to cost out your entire system. By adding engineering and cost libraries to a model, AFT products are a...

Don’t Repeat Yourself with Libraries

As process engineers, we rarely review our own engineering process for improvement opportunities. Our job descriptions can often boil down to: "design this", "build that", and "make it better". While we can do this very well for pumps, pipelines, and flanges, sometimes we miss the intangibles such as how to improve our team's internal processes or ...

Restore Your Sanity, and Your Corrupted Model Files

Users occasionally contact AFT saying they have lost their model files or cannot open them. Can you imagine spending hours, days, or months building models, and all of a sudden, the progress and work is gone?! If it happens right before a deadline, the engineer will most likely have a minor panic attack, and feelings of anger, depression, or hopele...

Calculate Pressure Drop Across Sharp-Edged Perforated Plates

Sometimes design engineers will install a screen to protect equipment like centrifugal pumps. Screens are available in a variety of configurations, each with its own head loss characteristics. AFT Fathom provides a screen junction that allows users to choose from four different screen types: Perforated Plate (Sharp-Edged)Perforated Plate (Round-Edged)Circular WireSilk Thread Screen This article primarily discusses thin-walled, sharp-edged perforated plates with uniform diameter holes. Every screen has an open flow area that allows the working fluid to bypass the screen while restricting any foreign objects that are not able to pass through this area. The open flow area is typically comprised...
