Jukka Aho 0d0d200bfc Incremental formulation works now, also finite sliding without proper linearization (very slow convergence) 2016-02-16 17:40:11 +02:00
Jukka Aho c7cca58590 test models and mortar stuff 2016-02-16 12:25:24 +02:00

Jukka Aho e7f29b3c5a playing with an idea, should we have separate file for every test to make development easier...? 2016-02-13 01:15:02 +02:00
Jukka Aho 1739e06014 prehook: calculate normal-tangential coordinates for elements before assembly and throw error if projection is going to fail 2016-02-13 01:13:38 +02:00
Jukka Aho f5b8608158 removed obsolete (and potentially non-meaninful) test routine for elements. for nonlinear geometry we need to have some good way to distinguish between initial and deformed coordinates 2016-02-13 01:12:24 +02:00

Jukka Aho aa7d775ec1 fixes 2016-02-03 20:39:03 +02:00
Jukka Aho 32e7429fd3 Major changes in data structures:
- Combined FieldAssembly and BoundaryAssembly to Assembly
- Combined FieldProblem and BoundaryProblem to Problem
- FieldProblem and BoundaryProblem are now abstract types
- Renamed stiffness_matrix, mass_matrix and force_vector to K, M, f for
  easier notation
- Problems are no more abstract types but concrete types, see
  elasticity.jl for example
- Combined linear_elasticity.jl and elasticity.jl
- Removed obsolete code directsolver.jl
- Almost all tests probably fail at this point
