Getting Started

Instructions

  1. Sign up for the trial to get access to our software.

  2. The intact CLI executable is installed in C:\Users[your username]\AppData\Local\Programs\Intact.Simulation for Automation\intact.exe

  3. Some demo examples (Mesh and VDB geometry).

Typical workflow

  1. Set up the input Json and provide the geometry file (.VDB, .PLY, .STL) and boundary condition faces (.STL, .PLY)

  2. Execute intact CLI $ intact -s “path to json file” –-save-solution –refinement-level 0.02

  3. A successful run will result into a *_samples.vtu result file

  4. You can visualize the result in Paraview (an opensource program, see instruction below)

  5. Resample the saved solution on a new geometry (sections or cuts)

    • Modify geometry file in the original JSON to the new geometry that you want to resample on

    • Execute $ intact -s “path to json file” –load-solution-file –refinement-level 0.02

Viewing Results

The intact command line outputs VTK files. These are fairly standard, and can be manipulated in a variety of programming languages. For more information about official VTK resources please check out their homepage.

VTK - The Visualization Toolkit

There are a number of third-party libraries for working with VTK files in other languages.

We recommend using the Paraview application for viewing and manipulating these results in most cases. Paraview is an industry-standard scientific data analysis and visualization tool that is free and open-source. More information, and builds for most operating systems, are available from the Paraview home page.

Paraview Quick-start

Opening Paraview should yield an interface that looks roughly like this.

The intact command line tool will place the samples in the results directory (by default, the same directory as the json file). Look for a samples *.vtu file and open it in Paraview.

Make sure the samples are visible in the pipeline browser by clicking the eye icon.

The sampled fields are available in the properties dropdown. For example the following would be typical of a linear elasticity scenario.

Here is how stress results would look. One can rotate and pan the viewport.
