Real Tools. Real Results. Really Free.

Professional-grade casting simulation at no cost, with no compromises.

Real Software. No Trial.

This is real simulation software, not a 30-day trial. PoligonSoft FREE uses the same FEM core as our commercial editions, delivering full accuracy for models up to 500,000 elements.

100% Offline & Secure

Run simulations fully offline. Your CAD models, material data, and results never leave your workstation. No cloud uploads, no telemetry, just complete control.

Backed by Free Training

Learn casting simulation from scratch with free step-by-step video courses. From setup to result interpretation, everything you need to tackle real production tasks.

Everything You Need to Simulate Solidification

Core tools for thermal analysis, solidification simulation, and defect prediction in casting processes.

Mesh Generator

Converts the CAD model into a finite element mesh of tetrahedrons.

  • Import in IGES and STEP formats
  • Optimization of mesh quality
  • Fast and efficient mesh generation

Simulation Setup

Prepare and configure the model for subsequent calculations.

  • Initial calculation settings
  • Process templates
  • Boundary conditions setup

Material database

Editable library providing temperature-dependent properties of alloys and mold materials.

  • Extensive list of metals and alloys
  • Wide range of mold materials
  • Customizable user records

Results Visualisation

Advanced visualization of 3D dynamic fields and 2D graphs.

  • Interactive 3D analysis
  • Transparency, isosurfaces, shrinkage
  • Custom graph creation

Solidification and Porosity Simulation

PoligonSoft FREE uses the same thermal solver as the paid version and calculates the dynamics of mold cooling by accounting for thermal conductivity, convection, and radiation.

• Temperature-phase fields
• Hot spot detection
• Shrinkage cavity formation
• Macro and microporosity
