A lot of code is moved to FEMBasis.jl regarding
calculating basis / shape functions of finite elements.
* add FEMBasis to REQUIRE
* remove obsolete files
* remove obsolete test files
* make integration point iterable
* loosen type definitions
* get length of element rather from basis than connectivity
* calculate midpoint of reference element
* wrong input argument to eval_basis! fixed
Change the code coverage to green.
* removed duplicate code
* Removed unused code
* removed unmaintained code
* DCTI + DVTI refactored
* discrete fields refactored and tested
* fields are now tested quite well.
* Removed obsolete code not used anywhere
* Element descriptions to common dictionary
* size in global const dictionary also
* Added coverage to sparse tools and removed couple unused functions
* get nonzero rows from SparseMatrixCSC
* bugfix: extending element basis now working and tested
* Removed two unused functions from elements.jl
* removed useless function
* Useless conversion
* remove elasticity assembly using ForwardDiff because it's not used anywhere'
* Added basic testing for NURBS. Fixed bug in NSolid interpolation.
* removed unused functions
* Removed some debug stuff
* renamed file
* removed field assembly posthook, i think not good idea at all
* test for nnz(K) == 0 and automatic determination of dofs
* Testing that solver is throwing error if having problems with boundary assembly
* Removed some unused options. Refactoring.
* Moved solver non-related code to elements.jl
* Removed custom exception (no need)
* unneeded postprocess code
* More tests for NURBS elements.
* Removed unfinished .mail parser
* proper use of Logging package
* also read results
* renamed test file
* create_surface_elements accepts surface name in String now
* bugfix: remove zero rows from constraint matrix after manually removing dofs from some boundary assemblies.
* New test, displacement 3d patch test
* skip displacement field in surface element splitting if not defined
* test element splitting and linear surface elements, fails.
* Bugfix: Xdmf, not XDMF
* removed nonworking tests, requires bugfix
* abaqus_read_results is not working -> bug
