Virtual Device v. 21 (for SIMION®)

Abstract: Virtual Device is an add-on software package to SIMION 7/8.0/8.1 and future versions. It covers several features not fully developed in SIMION such as graphical geometry (GEM) building, data analysis, and ion movement in a gas. Virtual Device was developed independently by SIMION user Dr. Sergei Koltsov, St. Petersburg Russia (HSE-Saint Petersburg).

Main Features
  • Build geometry (GEM) files graphically.
  • Analyze SIMION data recording data (e.g. histograms/spectrums, phase plots, resolving power, and mobility calculations)
  • Optional hydrodynamics version: Navier-Stokes gas flow solver for supersonic, compressible, invicid flow conditions (e.g. supersonic jet), explorting gas flow, pressure, density, temperature, and velocity PA's into a SIMION collision model.

Short Visual Overview of Virtual Device

The first program in Virtual Device is the 3D Editor:

Here, you can draw your electrodes using a selection of shapes. Each shape has various parameters that may be set. The system can be exported as a SIMION GEM file for loading into SIMION. (In the Hydrodynamics version of Virtual Device, gas flow boundary conditions can also be defined here in the same model and exported to the Virtual Jet flow calculator.)

The next main program is Data Analysis:

Data Analysis can load SIMION Data Recording results and perform various plotting and analysis functions, some of which are specific to mass spectrometry.

Special Hydrodynamics Version - Supersonic Jet Simulation

A more advanced version of Virtual Device is also available that supports the flow calculation and simulation of ion movement in a supersonic jet. See Virtual Device 21 Hydrodynamic Version.

NEWS! 25 April 2012 - New v21.1 demo version available.

  • Demo version: You can download a demo version of Virtual Device Hydrodynamics from the "Check for Updates" button on main screen of the SIMION 8.0 or 8.1 software. (If you do not have SIMION but want to demo the hydrodynamics version, e-mail us, asking for the demo.) You may use the Demo version for about one month for the purpose of testing the software (non-production work). If you're interested in gas flow calculations, be sure to see the Quick Tour of the Virtual Device Demo. Details on the latest version 21 Light are described in the online manuals above.

People who have purchased Virtual Device 18 are entitled to a free upgrade to Virtual Device 21 Light. Click the "Check for Updates" button in SIMION 8.0 or 8.1 to download the Virtual Device update.
