Your newly created model is opened after following the Creating your first project page. The opened model contains a lot of different buttons and drop-down menus. We will explain all these on this page.

1. The optimiser tab buttons

These buttons will bring you to the four different tabs the optimiser contains.

Button logo	Name	Explanation	More information

Name	Explanation	More information
Designer	This tab lets you work on the models	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089530882/Drawing+your+first+model
Inspiration library	This tab contains different pre-made and working models that you can insert into your model. This way you don’t have to start drawing your models from scratch.	New wiki: Inspiration Library - Wizard
Sensitivity analysis	Sensitivity analysis is used to thoroughly examine the correct dimensions of the system by simultaneously simulating different models, each having a minor difference from the reference.	Sensitivity Analysis
Pareto	Pareto analysis is used to analyse different concepts or models with each other. The analysation is done by comparing the KPIs (Key Performance Indicators) of every model.	Pareto analysis: usage

2. Log out button

This button lets you log out of the Hysopt optimiser application.

3. Layers and libraries

These buttons contain all the different libraries you need to make a working model.

Button logo	Name	Explanation	More information

Name	Explanation	More information

4. Tools

Button logo	Library	Name	Explanation

Button logo	Library	Name	Explanation
		Select	This is used to select one or multiple items on the drawing canvas.
		Two pipe	This is used to draw two pipes (supply and return). This is the kind of pipe that you as a user will mostly use.
		Header	This is used to draw a header. This pipe is used in places where one pipe arrives and multiple pipes leave.
		Reverse return	The reverse return pipe is used so that the length of the circuit through the supply and return piping to each end unit is essentially the same. Therefore, balancing is almost unnecessary.
		Changeover	This pipe can be used in a system where both heating and cooling connections are made through the same pipe.
		Three pipe	This piping offers a significant reduction in installation costs and pipework compared with traditional four-pipe systems. Three-pipe systems can provide full heating and/or cooling to any room at any time.
		Canvas Link	This is used to draw links between canvasses. This is needed as Hysopt is a 2D -modelling software.
		Draw zone	This is used to draw zones which you can assign to the Base circuit ‘Radiator/Convector’. A zone is the equivalent of the room where the radiator/convector is located.
		Assign to zone	Can be used to assign a radiator to a zone.
		Unassign from zone	This button can be used to unassign a radiator from a zone.
		Draw	Lets you draw control lines that are used to connect control base circuits or with base circuits.
		Assign to the electric meter box*	This button can be used to assign an electric consumer to an electric meter box.
		Unassign from the electric meter box*	This button can be used to unassign an electric consumer from an electric meter box.
		Assign to fuel meter box*	This button can be used to assign a fuel consumer to a fuel meter box.
		Unassign from the fuel meter box*	This button can be used to unassign a fuel consumer from a fuel meter box.
		Insert label	Can be used to create text labels where you can write your comments etc. in.
		Insert dynamic label	Can be used to create dynamic labels by clicking base circuits while this button is active.

* More info about the meter boxes is found on the page Meter boxes

5. Basic Circuit Library

This contains all the different base circuits you might need to draw a model. Base circuits are the building blocks of your model in which you can fill in specific properties of that base circuit. Base circuits can be divided into three major classes, namely production units, end units and in-between units. The illustration below shows a heating circuit on which these classes are indicated.

The difference between those classes is explained in the table below.

Name	Explanation

Name	Explanation
Production units	These BCs provide power to the circuit and has 1 node were you connect the pipes to.
In-between units	These BC’s makes it possible to add different hydraulic structures which require different calculations to your model. These blocks have 2 nodes where you connect those pipes to.
End units	These BCs consume the power of the circuit and has 1 node to connect pipes to.

In the table below you find all the BCs of the illustration with the classes and the library where to find them to explain the structure of the basic library. All of the BCs come from the heating library but don’t worry, the cooling library has the same structure.

6. Snippet library

As part of the Hysopt BC library, Hysopt also provides commonly-used configurations for a particular BC under the form of snippets. Snippets can be accessed by clicking the expand icon in the bottom-right corner of a base circuit in the library. The expand icon will open the snippet pop-up window with all available snippets for that particular base circuit. When selecting a snippet from the pop-up window, the snippet is pasted as a group onto your canvas. More information about snippets can be here: snippets

7. File buttons

Button logo	Name	Explanation

Button logo	Name	Explanation
	Open model explorer	The model explorer is used to open/create new models/folders, import models with tokens and move folders and models.
	Save model	This is used to save your model.
	Copy model	This opens a pop-up screen where you can give your current model another name and another location. This is the same as a ‘save as' function.
	Insert model	This can be used to insert another model in your currently opened model.
	Export as…	Exports the model as different file types. The possible file types are: JSON, PDF & DXF. More information about the export possibilities is found on the Exports page.

8. Model name

This is the name you gave your model during model creation.

9. Compute actions

Button logo	Name	Explanation	More information

Name	Explanation	More information
System check	'System check' will check the model for hydraulic mistakes and inconsistencies but this will not check the capacities.	System Check
Compute design flows	This action calculates the design flows based on the filled in parameters.	Compute design flows
Select pipes	This action selects the pipes based on the filled in parameters and filtering criteria.	Select pipes
Optimise components	This action optimises the valves and pumps.	Optimise components
Simulate	This action requires the use of components in the control library to simulate the dynamic behaviour of the system.	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367697/Dynamic+simulation

10. Canvas management, operations and model settings

	Model settings	This lets you change the units, diversity standard and many more settings of your current model.

11. User settings & Support buttons

Button logo	Name	Explanation

Button logo	Name	Explanation
	User settings	Lets you change user-specific settings.
	Help	Contains a link to the https://hysopt.atlassian.net/wiki/spaces/HRM or lets you contact one of our Hysopt experts.

12. Perspectives

To prevent the software from becoming too confusing, some buttons or parameters of base circuits are hidden behind layers. Perspectives are used to reveal these hidden layers.

Perspective logo	Name	Explanation

Perspective logo	Name	Explanation
	Advanced	Enables you to show or hide parameters classified as "Advanced”, allowing you to focus on essential, easy-to-understand parameters.
	Simulation	Enables you to show or hide parameters that are only relevant for simulation purposes. This layer is used to parameterise the dynamic behaviour of the installation.
	Partial load analysis	Allows you to analyse the model in partial load. This layer is mostly used to analyse balancing and valve authorities in partial load situations.
	Sensitivity Analysis	Allows you to highlight certain base circuit parameters that you want to adapt in a sensitivity analysis.

13. Drawing canvas

This is the space where you can draw your model. You can draw models by dragging and dropping base circuits on the canvas and connecting these by pipes and control lines.
