ImpressionFEA 0.6.0 by Marconnet Technologies LLC: richer results, a full view system, exports and reports, and die-only STEP import.

Downloads (Windows 10/11 x64, nothing to install)

File Contents Choose it when
ImpressionFEA-0.6.0-win-x64-full.zip (839 MB) NVIDIA GPU solver (cuDSS, CUDA 12 runtime, cuBLAS) + Intel MKL CPU solver you have an NVIDIA GPU (driver R525 or newer)
ImpressionFEA-0.6.0-win-x64-light.zip (209 MB) Intel MKL CPU solver only no NVIDIA GPU, or a smaller download; Get-GpuSolver.ps1 can add the GPU libraries later

Unzip and run ImpressionFEA.App.exe, then open the Demos tab. SHA-256 checksums are attached as .sha256 files.

What's new

  • Damage result (normalized Cockcroft–Latham, ductile tearing risk) in 2D and 3D.
  • Flow arrows: material velocity at every increment, 2D and 3D, with density and size controls.
  • View ▾ panel (live): workpiece and each die's visibility and opacity, lighting, section plane (axis, offset, flip),
    element edges, die-contact highlight (amber = bottom, magenta = top), colour map on/off.
  • Four-view layout (Top / Front / Right + isometric) and an XYZ triad in every 3D view; F fits the visible bodies.
  • Iso-clipping: drag the colour-bar handles to hide elements outside a value range.
  • Playback controls: play / pause / step / loop / speed.
  • Exports: WebM video of the ram descent (with FFmpeg) plus telemetry; deformed part as STL or coloured PLY; and a
    report generator that writes a self-contained HTML report (assumptions, setup, results, figures, telemetry, run
    comparison) with the CSV, setup, log, STL/PLY and video.
  • Die-only STEP import (two bodies) with a workpiece you define: shape, size, rotation, position. New demo 7 uses
    the gear-blank dies.
  • Compare runs: click any run in RUNS to bring its results back; Reset clears runs and telemetry.
  • US / Metric units (US default: in, ksi, tonf, °F to 3 decimals; metric: mm, MPa, t, °C to 2 decimals).
  • Esc aborts solves, multi-runs and exports; dialogs remember their folders; resizable panels.
  • Hex-flange demo now fills to 99.9 %.

See the CHANGELOG and
README.

Assumptions

Adiabatic walls (no heat lost into the dies) · no heat generated by plastic deformation or friction (hence isothermal)
· rigid-viscoplastic, incompressible material (no elasticity / springback) · rigid dies · constant shear friction ·
quasi-static forming. Results are engineering estimates for design comparison, not certified predictions.
