First public release of ImpressionFEA, a Windows desktop simulator for closed-die impression forging by Marconnet Technologies LLC.

Download & run

  1. Download ImpressionFEA-0.5.0-win-x64.zip below and unzip it anywhere.
  2. Start ImpressionFEA.App.exe. Nothing to install: the .NET runtime is included.
  3. Open the Demos tab → pick a demo → Load demo, then press Solve.

Requirements: Windows 10/11 x64. The multithreaded CPU solver (Intel MKL) is included.
Optional GPU acceleration (NVIDIA, CUDA 12 driver R525+): run Get-GpuSolver.ps1 in the app folder. It downloads
the NVIDIA cuDSS / CUDA runtime libraries (~880 MB) directly from NVIDIA and installs them next to the app.

Highlights

  • 2D and 3D forging simulation: rigid-viscoplastic finite elements, from fast axisymmetric / plane-strain runs
    to full 3D tetrahedral models, with press load, cavity fill, stress, strain and strain-rate results.
  • Your own CAD: import a STEP file with three bodies (bottom die, workpiece, top die). The workpiece is found by
    centre of gravity; you pick the moving die; the run continues until the dies touch.
  • CAD loop: Re-import notices when the STEP file changes and reruns with every setting kept.
  • Robust 3D solver: handles sharp die edges, adjusts the step size automatically, and refines the mesh
    locally when a step fails.
  • Multi-run sweeps (temperature, friction, ram speed, mesh size, material), with run history overlaid on the
    load / fill chart and CSV export of the telemetry.
  • Setups (*.ifea.json) to save and reopen jobs; 6 curated demos with in-app instructions. Demos are
    editable JSON files, so you can write your own.
  • SolidWorks-style 3D viewport (middle-mouse rotate / Ctrl pan / Shift zoom, Ctrl+1…7 views, F to fit).
  • GPU (NVIDIA cuDSS) or CPU (Intel MKL) sparse solvers, auto-selected by benchmark.

See the README and CHANGELOG for details.
