"Features" into the README

[Psirus]

I think it would be nice to have a short overview of what is NuTo suited for, what is it being used for and what is possible. I'm not saying we need this to attract users, but I think it would be nice if the "startpage" was a bit more meaningful to collaborators etc. So, maybe we can add a short list, in an ideal world even linked to an example, of NuTos features. From the top of my head:

---

Physics

• Mechanics
  • linear Elasticity
  • Viscoelasticity
  • Von-Mises Plasticity
• Damage
  • Phasefield Damage Model
  • Gradient-Enhanced Damage Model
• Heat Conduction
• Moisture Transport
• Mechanisms for easy coupling

Constraints

• Dirichlet node boundary conditions
• Linear constraints between nodes using user-defined equations

Math

• Block Matrices/Vectors with convenient per-independent-variable access

Parallelization

• Finite Element Tearing and Interconnecting
• OpenMP

Interpolation and Quadrature

• Most common quadrature schemes predefined:
  • Gauss/Lobatto
  • 1D/2D/3D
  • for simplexes and quadrilaterals/hexahedra
• freely combine interpolation order and element shape
• different interpolation order for each independent variable

Time integration

• Newmark
• Runge-Kutta (2, 3, 4, 3/8, Cash-Karp, Dormand-Prince)
• ImplEx
• VelocityVerlet
• Nyström
• Time dependent constraints & loads

Misc

• Fibre embedding
• VTK output
• Isogeometric analysis
• Mesh generator for simple meshes included
• Geometry generation for mesoscale concrete models

Feel free to add or remove things. In particular, I'm unsure what to say about Metamodel and Optimize, because I haven't used them.

I've just found this project Feedmereadmes, where they offer free feedback and editing for open source READMEs. Maybe we could submit ours once this issue has been completed.
