Lib-ICE
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 (www.engines.polimi.it). 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).
