1. Overview

With Simcenter Testlab Revision 18 and higher, both Simcenter Testlab and Simcenter Testlab Neo are delivered together. Some quick compatibility facts:  
  • Installation: The installation files contain both Simcenter Testlab “Classic” and Simcenter Testlab Neo software.  Both are installed during the installation process.
  • Licensing: The Simcenter Testlab Desktop license and token licensing can be used to run either Simcenter Testlab “Classic” or Simcenter Testlab Neo.
  • Data: Simcenter Testlab project files (*.lms) can be opened in both “classic” and Neo. For example, after opening the project file in Simcenter Testlab Neo, it can still be opened again in Simcenter Testlab “Classic”.
The functionality of Simcenter Testlab Neo has been increased with each subsequent release:
  • With Simcenter Testlab 2306 release, modal correlation and impact testing were added.
  • In Simcenter Testlab 2206, geometry creation and operational deflection shape analysis was added to Simcenter Testlab Neo.
  • In Simcenter Testlab 2021 release, Simcenter Testlab Neo included processing spectral data, sound quality metrics, and fatigue life from time files. Simcenter Testlab Neo Time Data Acquisition (not discussed in this article) can be used to acquire time data.

Over time, other functions like transfer path analysis and modal curvefitting will also become part of Simcenter Testlab Neo.

2. Getting Started

When double clicking on the Simcenter Testlab start icon, the start folder contains several selections as shown in Figure 2
User-added image
Figure 2: Start folder of Simcenter Testlab.  The Simcenter Testlab Neo applications are outlined in orange and contain the word “Neo”.  
The names of the folders indicate whether they are Simcenter Testlab “Classic” or Simcenter Testlab Neo:
  • Folders containing the word “Neo” start new Simcenter Testlab Neo.
  • Folders without the word “Neo” start Simcenter Testlab “Classic”.  

Examples of how to start Simcenter Testlab Neo and Simcenter Testlab “Classic” are shown in Figure 3.
User-added image
Figure 3: Left – The icon “Desktop Standard & Advanced” start Simcenter Testlab “Classic”.  Right – After opening one of the folders with the word “Neo”, the icon “Desktop Neo” starts Simcenter Testlab Neo.
The Desktop application can be started as follows for the two different versions:
  • Simcenter Testlab “Classic”: Click on the “Desktop – Standard & Advanced” icon in the start folder.
  • Simcenter Testlab Neo: Open one of the folders with “Neo” in the name and start the “Desktop Neo” icon.

The Testlab Desktop (both in classic and Neo) is used for viewing data. They have similar yet different features as shown in Figure 4.
User-added image
Figure 4: Simcenter Testlab Neo has a ribbon (right) that is like current versions of Microsoft Office products.  Both the Neo and Classic version of Simcenter Testlab also have workbooks that can be navigated along the bottom.
Simcenter Testlab Neo has a ribbon across the top, like the latest versions of Microsoft Office. Both software packages have navigation tabs along the bottom.

In the lower right corner of Simcenter Testlab Neo, there is a “Guide Me” button as shown in Figure 5.
User-added image

The “Guide Me” button provides a step-by-step instruction for performing tasks. The guide highlights the menus to be used in the order they are to be used.  Each tab has a different task.

3. Displays and Pivot Table

The display layouts of Neo and “Classic” are the same, just activated in different ways as shown in Figure 6:

User-added image
Figure 6: Display layout files are common between Simcenter Testlab Neo and Simcenter Testlab “Classic”.
The layout files are exactly the same between “Classic” and Neo.  If new custom displays are create in either version of software, they are automatically available in both versions.

3.1 Displays

Simcenter Testlab Neo has some added features to make displaying data more convenient:
  • Preview Pane:  In the display area, there is a tab called “Preview” which automatically shows data when it is selected. Shows multiple graphs automatically if more than one piece of data is selected.  
  • Auto-Display Settings: Simcenter Testlab Neo remembers display preferences for data (dB, amplitude, axis ranges, tick marks, etc) 

These features are shown in the animation in Figure 7.  
User-added image

Neither the preview pane nor auto-display settings was available in Simcenter Testlab “Classic”.

For more information, see the knowledge article: Simcenter Testlab Neo: Displays.

3.2 Pivot Table

Don’t drill so many folders!  The Simcenter Testlab Neo pivot table allows data from multiple data storage folders to be seen at once (Figure 8).
User-added image
Figure 8: Right – In Simcenter Testlab “Classic” multiple folders must be opened to see all data in a run.  Left – In Simcenter Testlab Neo, all data is shown in the pivot table for a selected run.
The pivot table summarizes all data found in the highlighted level of a project. The data can be sorted in the table by attributes, including function class, run name, point id, and more.

For more information, see the knowledge article: Simcenter Testlab Neo: Pivot Table

4. Processing

Simcenter Testlab Neo has data processing capabilities.  As of the Simcenter Testlab 2021 release, the processing mainly aimed at calculating spectral and fatigue results from time files.

Similar to Simcenter Testlab “Classic”, processing capabilities can be turned on via “Add-ins” as shown in Figure 9.
User-added image
Figure 9: Left – In Simcenter Testlab “Classic” processing capabilities are added to the Desktop via “Tools -> Add-ins” from the main menu bar.  Right – In Simcenter Testlab Neo, add-ins are activated via “File -> Add-ins” from the main menu.
The add-ins do not have the same names or functionality between Neo and “Classic”.  In both cases, the number of tokens to use a particular feature are shown in the add-in menu.

One of the key add-ins to process data in Simcenter Testlab Neo is called “Process Designer”.

The Simcenter Testlab Neo Process Designer is a new approach to processing data.  It allows users to chain “Methods” together to process time histories as shown in Figure 10.
User-added image
Figure 10: The Simcenter Testlab Neo Process Designer allows users to connect methods from a library to create comprehensive processing algorithms.
Methods are drawn from libraries.  Functionalities in the libraries include:
  • Conditioning: Filters, detrending, spike removal,..
  • Spectral Processing: Power spectral densities, averaged spectrums, spectral maps, order cuts   
  • Sound Quality: Loudness, modulation, equalization             
  • Fatigue: Rainflow counting, stress Life, strain life, damage
  • Logic: Select data for processing based on Y-axis unit (strain, acceleration, pressure,…), run names (steady versus runup), and other attributes.
  • And more….

Multiple types of processing can be performed this way with a single session. In Simcenter Testlab “Classic”, this might have required separate sessions.

For more information on the Process Designer of Simcenter Testlab Neo, see the knowledge articles: 

5. New Capabilities

New capabilities have been implemented in Simcenter Testlab Neo as well that were not available in "Classic" Simcenter Testlab.  Some examples include:

5.1 Video Replay

The “Video Replay” add-in of Simcenter Testlab Neo allows video to be played back simultaneously with any time data stored in the Simcenter Testlab project (Figure 11).
User-added image
Figure 11: Video can be imported and synced with time data for playback in Simcenter Testlab Neo.

Capabilities include importing the video, finding a common event to sync upon.  Video, sound, and other data can then be played together with synchronized cursors.

More information in the knowledge article: Importing Video in Simcenter Testlab Neo

5.2 Audio Replay and Filtering

Simcenter Testlab Neo includes audio replay, easy sound selection, live filtering, live spectrum visualization during replay, live colormap visualization during replay (Figure 12).

5.3 Amesim Simulation Models

Simcenter Testlab Neo also can directly utilize time files from the simulation software. An example with a Simcenter Amesim simulation software file (*.ame) is shown in Figure 13.
User-added image
Figure 13: Simcenter Testlab Neo can view and process time data from simulation software including Simcenter Amesim.  In addition to the time data, the sketch view of the Simcenter Amesim model (upper right) can also be viewed and used to select data.
Time history data can be used from numerous simulation packages:
  • Simcenter 3D Motion (*.mres)
  • Simcenter Amesim (*.ame)
  • Universal files (*.unv)

Outputs and inputs of a model can also be part of Simcenter Testlab Neo Process Designer.  Using the Functional Mock-up Interface standard (, the following can be accessed:
  • Inputs: Test time data can be used as input to a simulation model
  • Outputs: Newly solved time domain outputs of a simulation model
  • Model Parameters: If exposed in the interface, model parameters can be adjusted from Simcenter Testlab Neo.  For example, the spring rate of a damper could be adjusted and the results calculated.

To use the Functional Mock-up Interface, a *.fmu file needs to be generated from the simulation model. A solver license might be required as well.

For more information, see the knowledge article: Accessing Simcenter Amesim Models in Simcenter Testlab.
