Your newly created model is opened after following theCreating 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.

5. Hysopt Library

5a.

...

Base 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.

...

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.

5b. 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 Image Added 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

6. File buttons

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 inforamtion information about the export possibilities is found on the https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367755/Exports page.

Name	Explanation	More information
System check	'System check' will check the model for hydraulic mistakes and inconsistencies but this will not check the capacities.	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089203395/Model+validation
Compute design flows	This action calculates the design flows based on the filled in parameters.	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367213/Compute+design+flows
Select pipes	This action selects the pipes based on the filled in parameters and filtering criteria.	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367328/Select+pipes
Optimise components	This action optimises the valves and pumps.	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367389/Optimize+pumps+and+valves
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

Button logo	Name	Explanation
Image RemovedImage Added	Canvas selection and management	Canvas management & Floor plan implementation
Image Added	Layers	This button can be used to toggle different visualisation layers. For example, the Hysopt user can choose to hide zones, text, controls, grids, or floor plans on the active Canvas
	Create report	https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089367755/Exports
	Search	Can be used to search for components in your model.
	Operations	Gives a screen of different operations you can use and the shortcuts for these operations.
	Model settings	This lets you change the units, diversity standard and many more settings of your current model.

Perspective logo	Name	Explanation
Image Added	Advanced	Enables you to show or hide parameters classified as "Advanced”, allowing you to focus on essential, easy-to-understand parameters.
Image Added	Simulation	Lets you change user simulation-specific parameters on base circuitsEnables 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.
Image RemovedImage Added	Partial load analysis	Lets Allows you to analyse the model in partial load. This layer is mostly used to see analyse balancing and valve authorities in partial load situations.
