IST Vector Postprocessor

IST Vector Postprocessor turns raw simulation output into clear, presentation-ready insight. Built for engineers and researchers working with finite-element and mesh data, it pairs a fast GPU-accelerated 3D viewport with the analysis depth a serious post-processing workflow demands.

Open your data, instantly. Native readers for EnSight Case (ASCII and binary), VTK unstructured grids (.vtu), PolyData (.vtp), legacy .vtk, ParaView collections (.pvd), and Wavefront .obj — with automatic format detection and full transient, time-series support.

Interrogate every field. Visualise scalar, vector, and tensor results directly, or derive what you need on the fly: von Mises and principal invariants, deviatoric and component decompositions, vector magnitudes, nodal recovery, and error estimates — over a perceptually-uniform colour scale you control.

See the physics. Iso-lines and iso-surfaces, streamline tracing, threshold filtering, deformation warping, and symmetry expansion, framed by automatic best-view selection, saved views, and smooth animated camera tours. Studio lighting and filmic tone-mapping make every frame look finished.

Ship the result. Export crisp, vector PDF figures and high-quality MP4 video straight from the viewport — ready for a report, a paper, or a presentation.

No setup tax. A self-contained, ahead-of-time-compiled native application for Windows and Linux: no .NET runtime, no framework, no dependencies to chase. Download, run, done.
