Slicing is very expensive operation on sparse matrices. Avoid slicing
by calculating matrix product `K_red = C1*K*C1`, where C1 is diagonal
matrix. This should be much cheaper.
Now style is to assemble all same kind/dimension elements at same time
in one function call, so it's possible to allocate all necessary
matrices only one time.
This function can be used to create elements from node set defined
in mesh. Resulting elements are of type Poi1, that is, they don't
have any volume but it's still possible to add boundary conditions
to them which are then enforced in discrete sense.
Problem arises typically when boundary condition is created using
"nodal" elements of type Poi1, but forget to define geometry and
```solvers("geometry", 0.0)``` fails in Xdmf update function. Fixed.
Yet another loop, but this way we can preallocate matrices when
constructiong local matrices of elements with same dimensions (which is
the case in practice)
A lot of old files from old documentation systems etc. is in package.
These are now removed or moved. Old notebooks are in docs/tutorials.
This PR closes issue #124.
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
Source code related to read and parse ABAQUS .inp files is now living in
it's own repository `AbaqusReader.jl` and in this commit we cleanup the
same files from this repository.
- add AbaqusReader to .travis.yml because it's not registered package yet
- initialize Mesh from AbaqusReader.jl dict
- remove ABAQUS tests and files moved to AbaqusReader.jl
- remove references to old module Abaqus
- move ABAQUS code to preprocess.jl (what is left)
- close issue #122
- close issue #55
* running v0.6 conversion code proposed by @ovainola in #108.
* change travis so that build is done using 0.6
* documentation is build from 0.6
* fix most of deprecation warnings
* fix test to pass 0.6
- remove some automatically generated stuff not should even be in
repository
- set up lint + Documents.jl in same way it is defined in freshly started projects
- add lint + doctest to after_success so that build pass, these needs to be fixed later
- build is failing on nightly (0.7) but it's ok for release (0.5.2)
- Documenter.jl supports doctests, so this closes least #23
- build system is now on Travis-CI completely, so this closes also #68
- MED file actually supports multiple element sets or node sets for
single element/node. This is now implemented.
- Minor cleanup of code, etc..
- Fixes issue #111.
