TenGun™ Point Cloud / Mesh Preprocessor & Postprocessor

TenGun is a software tool used to preprocess and postprocess point cloud and CAD mesh data. Although initially developed for Smoothed-Particle Hydrodynamics (SPH), TenGun can also along side CFD, DEM, and similar engineering analysis methods. And TenGun also contains many features useful for manipulating a number of CAD file formats.

A common use of TenGun is when working with die casting simulations for automotive parts. TenGun makes it easy to create the simulation input, and then to visualize metal flow, thermal behavior, stress, strain, pressure, and other analysis results.

A complete analysis cycle involves creating the input model from a set of CAD mesh files, running your custom analysis application or an existing package, viewing the output, and usually creating presentation materials such as charts and videos. TenGun helps you with the pre and post-analysis steps so you can concentrate your engineering expertise on the analysis portion. TenGun also has a highly focused user interface, so you avoid feature bloat and a long learning curve.

TenGun's main features are described below.

Time Series Mode (Postprocessing)

Analysis applications typically generate a number of timestep-based particle (point) output files containing particle positions, velocities, pressure, temperature, and other relevant analysis results. TenGun is then used to visually verify those results. Major Postprocessing features include:

Flexible input file handling. Easily define additional text input file layouts in minutes. Use with your own application, commercial applications such as LS-DYNA, and with Open Source applications such as OpenFOAM and LIGGGHTS.
TenGun handles industrial-sized analysis results containing tens of millions of particles in multiple time steps.
Filter values using field name and range expressions to display specific details.
Cut (slice) the results one or more times to inspect the inside of the model.
Emphasis on ease-of-use, and without a bloated User Interface.
Easily create analysis presentation material.
Animated playback. Play back a series of analysis output files.
Create a movie file from the animation output.
Convert point cloud analysis results to a mesh for 3D Printing.
Automated report creation.
Multiple chart types: Frequency Distribution (bar chart or line chart), Line Chart, Scatter Diagram, and Timeline with statistics.
Copy Screenshot to file or to Clipboard for use in other documentation.
Easily customizable "Display Profiles" that allow definition of user-specific input file layouts, colors, labels, and other settings.
High-performance, even with large datasets.
Multi-lingual. English and Japanese are currently available.

Assembly Mode (Preprocessing / CAD Modeling / CAD File Conversion)

TenGun can create input data for various analysis applications. This typically involves assembling a model from a collection of parts created either with TenGun or another CAD tool. Next, you apply application-specific parameters such as timing control, material properties, boundary conditions, and so on. Finally, the assembly is exported in the form required for your analysis application, which often means converting meshes to particles.

TenGun simplifies these preprocessing activities with these features:

Create custom CAD objects for use as particle containers using built-in basic shapes such as boxes, pipes, wedges, revolutions, extrusions, and others. For many cases you can use just TenGun and therefore avoid having to use a separate CAD application.
Edit CAD object geometry, and combine objects with Boolean Operations.
Import assemblies and parts in various CAD file formats including IGES, LS-DYNA, OBJ, PLY, STEP (ISO 130303-203, 130303-214), and STL.
Convert CAD data between various formats such as STEP and IGES to simpler formats such as STL, and convert between OBJ, PLY, and STL.
Export assembled CAD models to your favorite application for fluid, solid, thermal, or other analysis. TenGun converts CAD objects to particle format during this process.

Text Editor

TenGun contains a built-in, full-featured text editor to handle those other editing tasks related to your analysis or other work.
