Further evolution
New user interface elements in SimulationX 4.1

Further evolution of the Ribbon user interface

Since version 4.0 the new context sensitive and clear ribbon interface is available in SimulationX. Based on the many feedback from our users, we have further improved the user interface for SimulationX 4.1:

  • New ribbon "Post Processing": Here you will find all the tools you need for evaluating results (charts, animation, ...) or exporting data (report generator, C code).
  • Customization of ribbons: Customize the interface to your needs and create your own ribbons or tool panes.
  • Direct input of start and stop time: The simulation Start and Stop time are now available in the ribbon bar in the new tool pane "Simulation Time". You immediately see the settings and no longer need to open the Simulation Control or the properties dialog to change these values.
  • Better cleanup: In the Backstage Area (Open), you can remove unfixed files from the list with one single click.
  • Better overview of open model views: Views belonging to the same model (file) (e.g. Diagram View and 3D View) are now highlighted in color. This helps you to find the corresponding views more quickly if several models are open.
New Save option

New Save option: Include Global Types (libraries) in the ISX files

Many simulation projects require the creation of customer- or project-specific model libraries, on the basis of which the simulation models are created. This implies various challenges:

  • Easy "packaging" of those simulation models with the corresponding libraries
  • Safe library and model transfer between users
  • Make sure the model and version of the library match
  • Protection of workflows from misuse or failures

SimulationX 4.1 masters all these challenges with the new "Save As" option "Include unencrypted Global Types". All unencrypted libraries, that the model actually is using, are placed in the ISX project file. No complete copies of the libraries are created, but libraries that only contain what is needed. The model itself is not changed.

When loading such ISX files, you may then choose whether you want to use the included library or an existing library.

This functionality replaces the "Resolve external references" tool.

Analysis platform: New Pre- and Post-Processing tools

New “model” library

SimulationX 4.1: New library Pre- and Post-Processing Tools (left) and optimization of an hydraulic aileron control (right)

New “model” library with various Pre and Post Processing tools

Many tasks for the preparation (pre-processing) or postprocessing of data in the simulation can be automated. SimulationX 4.1 introduces a new "model" library with corresponding tools:

Library General -> Sublibrary Pre- and Post-Processing Tools.

The elements of this library do not represent physics, instead they create interfaces to methods with which you can, for example, perform optimization tasks or generate ordercuts (see the following sections). Even your own methods, based on the script language Python, can be easily integrated into SimulationX.

All methods (tools) require a variety of parameters or are based on data from the model. Their integration into model elements guarantees their reproducibility and their belonging to certain models.

Ordercuts and Spectrogram

Ordercuts and Spectrogram for Vibration Analyses

Create Ordercuts or Spectrograms of your time-related simulation results quickly and easily. You have the choice between an order or a frequency analysis.

Many other options, such as the resolution of the order or frequency cuts or settings of the window function (e.g. "Kaiser-Bessel") allow you to adjust the presentation to your special requirements.

Optimizing and fitting
Adaptation (fitting) of unknown motor parameters to a reference system in SimulationX 4.1

Optimizing and fitting parameters

The Optimizer tool allows you to fit parameters of your model to target functions (e.g. measurement curves) or to optimize parameters (e.g. controller parameters). There are currently 5 optimization methods and a large number of strategies and options available.

SimulationX 4.1 supports you in the application with a series of examples and a tutorial.

Creating a 2D map

Creating a 2D map for the evaluation of a variant study

There are always tasks in which you want to investigate how a result (value) changes depending on two independent parameters of the system. The solution is a 2D map.

Using the Generate 2D map tool, you can easily generate a variant study according to the z = f(x,y) principle. The result is then either printed as an image, imported into the element (data) and optionally saved in a file.

System Reliability Analysis: Integrate behavior deviating from the nominal condition in system simulations

Analyze the effects and interactions of tolerances, wear, failures and other effects that lead to deviations from the nominal behavior of a system. System Reliability Analysis offers you modelling and analysis tools for this purpose.

Systematically evaluate the effects of different deviations and errors on system behavior, the interactions between occurring errors and their intensities in a transparent and repeatable manner using the tools of this module.

In SimulationX 4.1 we have extended the module with many new model components and functionalities:

There are now new elements for the Signal Feature Extraction or for the representation of component faults in hydraulic or pneumatic systems. The improved interface and the improved algorithms and workflows of the add-in increase the efficiency of the analyses, user-defined fault models are now also considered by the add-in.

Co-Simulation Interfaces

New Co-Simulation Interfaces for Siemens® PLCSIM Advanced™

New Co-Simulation Interfaces for Siemens® PLCSIM Advanced™

The new Modelica-based Co-Simulation library PLCSIM Advanced Interfaces as part of the library Generic Interfaces for SimulationX allows for Co-Simulation between SimulationX and the Siemens software PLCSIM Advanced.

Run Software-in-the-Loop tests (SiL) of a controller simulated in PLCSIM Advanced by Siemens and the automation object simulated in SimulationX.

One of the advantages of SiL is that the test is based on fully virtualized system components and can therefore be performed before the procurement and construction of the same. The co-simulation partners work on a virtual time basis so that the simulation is no longer carried out in real time making the requirements for real-time capable models obsolete.

Simply connect your model with the corresponding co-simulation interface elements and start your SiL test.

Economic Analyses
Total costs simulation for the operation of a PV system and an electric vehicle in SimulationX

Economic Analyses in System Simulation

Calculate and simulate costs and revenues based on (physical) result quantities, which are available in your model. Thus, for example, the electrical (power) output obtained (+) or consumed (-) can serve as the basis for a revenue calculation in electricity production or a cost calculation in electricity consumption.

The new Signal Blocks library Economic Analyses provides signal blocks for your system models. Consider costs of energy, bulk, pieces, volume (fluid), time, maintenance and renewal as well as the ROI. The icons visualize your preferred currency.

New Centrifugal Pump model

New Centrifugal Pump model in Hydraulics libraries

The new centrifugal pump model in the hydraulics library allows you to analyze hydraulic circuits even more efficiently, such as cooling circuits. The new model represents all 4 operating areas of the pump and is also suitable for simulating standing systems.

New symbols for the Pneumatics libraries

Meaningful icons make a significant contribution to quickly grasp the structure of models and their condition in the Diagram View. This simplifies modeling and helps to understand the system model.

The model elements from the Pneumatics, Vehicle Pneumatics and Hydraulic Lubrication libraries now communicate additional information in the Diagram View via their icons. In this way, you recognize details about the state of the modelled system at a glance. This includes information about the parameterization of the individual elements as well as their state during simulation.

Belt and Pipe Conveyors library

Belt and Pipe Conveyors library: New analysis and presentation tools

With the Belt and Pipe Conveyors library, you can design and test belt conveyor systems in the mining industry, including their drives and associated control technology, on a virtual basis. Based on customer feedback and new experiences in the applications, we continuously extend and improve this library:

In SimulationX 4.1 you now have the possibility to add a protocol element to the model. There you immediately recognize certain important parameters which are determined during the simulation. In addition, there is now an element with which you can detect whether the belt lifts off in a defined section during the analysis (incl. animation).
