Our vision, goal and what we do

Simulations heat and mechanicals stress of FCC metal in multiscale framework.
Simulations heat and mechanicals stress of FCC metal in multiscale framework.

All levels from atomistic to macroscopic Ability to develop and implement new methods, if needed Capacity to conduct multi scaling

Practical applications:

  • Mechanics
  • CFD (turbulent & laminar)
  • Heat transport
  • Electric and magnetic fields
  • Chemical reactions
  • Acoustics
  • Multiphysics combinations of these phenomena!
