#### assemble!(fe, eldofs_, I, V) [¶](#method__assemble.1)
|
||||
Assemble global RHS to I,V ready for sparse format
|
||||
|
||||
Parameters
|
||||
----------
|
||||
fe : local vector
|
||||
eldofs_ : Array
|
||||
degrees of freedom
|
||||
I,V : Arrays for sparse matrix
|
||||
|
||||
Notes
|
||||
-----
|
||||
eldofs can also be node ids for convenience. In that case dimension
|
||||
is calculated and eldofs are "extended" to problem dimension.

#### eliminate_boundary_conditions(dirichletbc, I, J, V) [¶](#method__eliminate_boundary_conditions.1)
|
||||
Eliminate Dirichlet boundary conditions from matrix
|
||||
|
||||
Parameters
|
||||
----------
|
||||
dirichletbc : array [dim x nnodes]
|
||||
I, J, V : sparse matrix arrays
|
||||
|
||||

-------
|
||||
I, J, V : boundary conditions removed
|
||||
|
||||
Notes
|
||||
-----
|
||||
pros:
|
||||
- matrix assembly remains positive definite
|
||||
cons:
|
||||
- maybe inefficient because of extra sparse matrix operations. (It's hard to remove stuff from sparse matrix.)
|
||||
- if u != 0 in dirichlet boundary requires extra care
|
||||
|
||||
Raises
|
||||
------
|
||||
Exception, if displacement boundary conditions given, i.e.
|
||||
DX=2 for some node, for example.
