Jukka Aho b950ba312a Replace some rarely used functions (#188)
- `empty!(problem)` -> `empty!(problem.assembly)`
- `get_gdofs(element, ndim)` -> `get_gdofs(problem, element)`
v0.3.7

Jukka Aho d2d860ccf9 Update docs
Let's try this kind of approach where JuliaFEM.jl documentation
is collected from other packages. May work or then not.

Jukka Aho dce7472cda Make JuliaFEM to use Analysis type from FEMBase
`Analysis` is basically doing same than `Solver` before, but has a
slighly simpler structure and is more general.

Jukka Aho d7bef419ed use FEMBase v0.1.x (#185)
Lots of stuff moved from JuliaFEM.jl to FEMBase.jl.
v0.3.6
2018-01-19 21:01:33 +07:00
Jukka Aho 35307b12ad Update REQUIRE v0.3.5 2017-12-27 19:43:49 +02:00
Jukka Aho 3e8fb609e6 remove matplotlib dependency
matplotlib cannot be installed during the generation of documentation,
ssl error. Use static images in documentation instead of automatically
generated ones.
v0.3.4
2017-11-13 11:48:17 +02:00
Jukka Aho 24a4e34370 add FEMBase.jl to REQUIRE 2017-11-13 11:48:17 +02:00
Jukka Aho 1693aa30ad Moved core functionality to FEMBase
Core functionality is moved to base package called FEMBase.jl. The
aim is that when developing new elements, solvers, materials and so on,
user only imports FEMBase.jl and uses the functionality there.
JuliaFEM.jl is a sort of "metapackage" collecting together all the
packages and features can be programmed in smaller packages focusing
only on one thing. This structure makes it attractive to contribute
smaller amount of code e.g. in the form of thesis. Moreover, FEMBase.jl
is under 2000 lines of code, which will be very clearly documented thus
everyone can understand the basic concepts behing JuliaFEM easily.

v0.3.3
2017-08-23 15:53:01 +03:00
Jukka Aho 2bb66a9568 Special handling of constant metric Tet10
Mass matrix can be analytically solved if Tet10 metric is constant, i.e.
the midnodes are in the midpoint of corner nodes. This should increase
assembling speed of mass matrix.

Jukka Aho a08a928796 Eliminate Dirichlet boundary conditions differently
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.

Jukka Aho 6e036878c8 Use global timer to measure performance
This makes syntax a little bit easier. Also, measure more accurately performance
of modal solver under investigation.

Jukka Aho e839c60904 Preallocate matrices in Elasticity problem
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.
2017-08-18 23:27:26 +03:00
Jukka Aho 90fd63f375 New function group_by_element_type
Function groups a list of elements to several lists, where each
list contains elements of particular type.

Jukka Aho 115b621938 Fix deprecation warnings when using Julia 0.6.0 2017-08-18 17:45:52 +03:00
Jukka Aho bec6642693 Assemble several elements at a time
Now assemble! takes a vector of elements as input. This makes it
possible to preallocate memory for common matrices making code super
fast.

Jukka Aho b1cf7eacb9 Implement new function create_nodal_elements
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.
2017-08-17 15:53:20 +03:00
Jukka Aho 741bb8d057 Fix test
Now both JuliaFEM and JuliaFEM.Preprocess export add_elements! and
it must be spesifically pointed out which one is used in test.
2017-08-16 17:20:55 +03:00
Rapo 683c0a03e6 Implement new function add_elements!

Jukka Aho 8ca459fc3a Remove functions used rarely
A new problem can be defined with 8(!) different styles. Let's remove
the ones not used often.

Jukka Aho 2ffe1589d7 Templating data type of Field

Jukka Aho 7a827e0a12 Fix return types for fields not defined
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.
