MUESLI

MUESLI is an open-source, object-oriented library of material models at the continuum scale.

🔑 Key characteristics

  • Object-oriented design of materials families, easily extensible.
  • High-level of abstraction in the operations based on tensor classes.
  • Automatic tests for certain functions (energies, tangents, etc.)
  • Interfaces with ANSYS, Abaqus, LS-DYNA

Material Models

  • Small strain mechanics elasticity, viscoelasticity, plasticity, viscoplasticity.
  • Finite strain mechanics hyperelasticity, plasticity, damage
  • Thermal materials (small strain isotropic).
  • Thermo-mechanical materials in the small and finite strain regime
  • Fluids (Fourier-type heat conduction).
  • Diffusive materials

🧪 Testing

MUESLI provides a series of automatic tests that can be employed, up to a certain extent, to verify the implementation of new material classes.

🛠️ Interfaces

  • MUESLI is code agnostic. It can be used in finite element, finite volume, finite difference, etc. codes, simply by providing the appropriate interface.
  • Currently, interfaces to Abaqus, LS-DYNA and ANSYS have been implemented.

🎯 Philosophy

  • Focus on clarity and extensibility over raw speed.
