Fluent TPA is a completely unique approach to working with Transfer Path Analysis. It originates from the idea that every TPA analysis can be brought down to essential processing steps on datasets (operational data or transfer function data), often formulated as matrix equations (linear algebra). Fluent TPA provides you with the building blocks for these matrix equations, combined with steps that focus on batch processing. As such, it combines the power of SOURCE to efficiently handle large data collections, with the freedom to decide on your own specific analysis.
When working with Fluent TPA you have to imagine yourself in front of a blackboard writing steps and equations of your workflow. We made Fluent TPA in such a way that when you write an instruction in the editor, you have to organize it as if you are writing an equation on paper, so by adding terms and operations one after the other.
A Fluent TPA analysis works like any other analysis in SOURCE concerning analysis creation, inputs, settings and computing.
To create a new analysis, complete the following steps:
The inputs and settings of the analysis are defined in the Inputs (link) and in the Settings (link), respectively.
To compute the analysis, within the Analyses card, you have to:
SOURCE will only compute the sections of the analysis that are set as active in the Fluent TPA editor.
To access the Fluent TPA editor, you have to:
You can name scripts according to your liking. The name of the script will appear in the script and in the analysis.
To name a script, complete the next steps:
After creating a script in the Fluent TPA editor, you can easily save it and export it to use in a different project or share it with a colleague.
To save a script, complete the next steps:
You can load an already existing Fluent TPA script in the editor.
To load a script, complete the next steps:
In your script, you can define multiple sections that you can rename and activate or deactivate according to your needs.
To add a new section, complete the next steps:
Clicking on the – button will remove the last section.
To rename a section, complete the next steps:
By default, all the sections added in the editor are set as active and are computed by SOURCE. You can deactivate sections so that they do not get computed. All instructions that are part of a non-active section will not be computed, so the variables created in a non-active section cannot be used in the next active section.
To deactivate sections, you have to:
Each line in the section is called instruction. When you write an instruction in the Fluent TPA editor, you have to organize it as if you are writing an equation on the blackboard, so by adding operations consecutively.
To add an instruction, you have to:
After creating an instruction, you can decide whether you want to visualize the outputs of that specific instruction in the results section. By doing it, SOURCE will create a new category in the results. You can create and rename the result category in the Fluent TPA editor.
To create a new category containing the outputs in the results, complete the next steps:
You can also create a new category by typing the desired name.
When computing the results, you can define the name of the results in that category. Instead of manually typing a name (which could lead to confusion in case of multiple inputs), you can use the tokenizer.
To setting the result names, complete the next steps:
Each building block of an instruction is called an operation. Three operation types are defined:
There are some general rules regarding operations in an instruction:
To add operations in an instructions, complete the next steps:
