Mortar FE on nonmatching grid
University of Augsburg
The package includes an example mortar finite element code for solving
Poisson equation on nonmatching grids. The code is based on the variational
formulation where the finite element solution is sought in a constrained
space (the functions of this space satisfy a weak continuity condition across
the interfaces) resulting in a system of equations whose coeffecient matrix is
symmetric and positive definite.|
Two types of test spaces (Lagrange multiplier spaces), for the
'weak continuity' condition, are provided: the standard- and the dual-
Lagrange multiplier space.
Set the correct path for the string variable 'MORTROOTDIR'
in the file 'installmort.m'. Run 'installmort' at matlab
prompt to include all necessary paths.
Playing with the code:
Write 'ellipmort' at the matlab prompt to run the code.
The driver routine is 'ellipmort', read the file 'ellipmort.m' and
make the necessary changes (model, discretization, etc.), in the
'User specification area' of the code.
Write 'help READMEmort' for more informations and restrictions.
