Lib-ICE is a set of libraries and solvers based on the OpenFOAM® technology for the simulation of:

  • In-cylinder flows in IC Engines;
  • After-treatment systems in IC engines;
  • Fluid Machines;
  • Flows in porous media;
  • Thermal management.

Lib-ICE is developed and released by ICE Group of Politecnico di Milano ( With a fully sinergic approach, Sursum-Mi offers dedicated Lib-ICE services, including: 

  • Training for specific applications: tutorials, case preparation, documentation; 
  • Dedicated pre- or post- processing tools for mesh generation, case setup, analysis of results; 
  • Code customization; 
  • Integrated simulations (CHT, 1D-3D).
