Instructions for use:

1. Create, open and import the model:

1. Create a new model file and start assembling the new model:

On the ribbon, click the "File" tool, or select "File"> "New" from the menu bar.

A new modeling window will open for you to create a model.

2. Open the model to open an existing .scm model file:

On the ribbon, click the "File" tool:

In the "Open File" dialog box, navigate to your working directory and select a .scm model file.

The model file will open in a new window.

3. Save the model to save the current model:

On the ribbon, click the "File" tool: or select "File"> "Save" from the menu bar.

The current model is saved with the extension .scm. This is a text file that contains the entire model definition. If the model has not been saved before, the "Save As" dialog box will open for you to name and save the model to the working directory.

4. Import block:

Loads the block into the current model as an inline .scb file that does not reference the library or source definition.

The import option can inline a block .scb file so that the file neither points to nor depends on the block definition in the library source. This operation does not display the block icon.

In the menu bar, select File>Import.

In the Import File dialog box, navigate to the blocked file you want to import, and select Open.

The imported block will be inserted into the current model .scm file.

2. Browse the model Navigate:

within the model hierarchy and between multiple diagrams.

You can browse the model hierarchy in three ways: from the diagram displayed in the modeling window, from the project browser or from the navigation bar. The example below shows you the main image of the bouncing ball model and the options for navigating in it.

1. Modeling window:

Double-click the super block in the main diagram of the model.

The main diagram closes and displays the diagram inside the super block. You can continue to drill through each layer of the super block in this way.

2. Double-click the super block on the tree in the project browser:

The blocks inside the super block are displayed in the tree and in the modeling window.

3. Click the navigation icon on the navigation bar:

The navigation will open and list the main graph and its associated super blocks.

Software function introduction:

1. Result Viewer:

Through the "Result Viewer", you can view the data of all blocks, including Modelica blocks and FMU. To generate a result file (.mtsf), select the "Create Result File" option in the "Simulation Preferences" and then run the simulation.

2. Modelica:

1. Modelica compiler: The

compiler now uses different weights for default and user-defined input values ​​to improve variable initialization.

2. Modelica Extras palette. The new Modelica Extras palette contains the Activate utility block, which can be used with Modelica in the Activate model. The new organization provides easy access to commonly used block sets.

3. Modelica block The

Modelica library provides new blocks:

• Modelica Expression (MoExpression): The output of this block is a real scalar value obtained by evaluating the Modelica expression specified as the block parameter. The expression is given in terms of variables u1,...un (unless a custom input name is used), where ui is the i-th scalar input.

• Modelica constraint (MoConstraint): The module outputs a Modelica signal, so its input remains zero.

• The "Block" category of the Modelica Standard library can now be accessed from the Modelica panel.

3. Spice simulation:

1. Use Spice model to perform AC analysis.

This function is suitable for super blocks that only contain HyperSpice blocks. Dedicated blocks can be used to define AC analysis options (frequency) and required output (curve). The voltage source module in the HyperSpice library has been expanded to allow the definition of AC power properties.

Four, fluid hydraulic Fluidon hydraulic block

The following new blocks are provided in the Fluiding by Fluidon library:

• ResistorTableQp: A resistor with a lookup table Q (Δp).

• ResistorTableQpx: A resistor with a look-up table Q(Δp, x).

•ResistorTableAx: Resistance with look-up table, used to look up the cross section of valve opening A(x).

• PropValveXXPT2TableAx: Directional valves 2/2, 3/3, and 4/3, with a look-up table for the cross-sectional

metering edge of each valve opening A (x) .

• PropValveXXPT2TableQpx: Directional valves 2/2, 3/3, and 4/3, with look-up tables, for flow Q (Δp, x) at each metering edge.

Hydraulic system of Fluidon model:

 The following new circuit models are available in the Fluiding by Fluidon library and can be accessed from the "Demo Browser".

The following new functions are provided in the block activation library:

• FormattedString: This block simulates C/C++ snprintf function. • Encoder: This block is available in the Arduino library.

Sixth, user interface and block diagram editor
