ALBERTA-2.0 UNRELEASED ALBERTA 2.1-Beta
- per default ALBERTA installs itself into the directory
hierarchy below "/usr/local/". Previous versions of ALBERTA
installed themselves into the build-directory.
- separate graphics and "core" ALBERTA libraries, and a
global configure-time graphics kill-switch
"--disable-graphics".
- BLAS is not used by default, but can optionally be enable by
running configure with the "--enable-fortran-blas" switch.
- easy-to-use (iso-)parametric meshes, up to piecewise polynomial - easy-to-use (iso-)parametric meshes, up to piecewise polynomial
degree of 4 degree of 4. The coordinate vectors are now dumped to disk
along with the mesh-structure when calling write_mesh().

called before doing any mesh-refinement.

"--disable-graphics". ALBERTA 2.0
- support of submeshes, DIM constant removed
- support of iso-parametric meshes up to p.w. polynomial degree 2
- more generalized node projection mechanism
- graphics output interface to GMV
- discontinuous basis functions up to degree 2.
- get_fe_space() works at any time
- INDEX macro only available for ALBERTA_DEBUG=1
- NEIGH_IN_EL, EL_INDEX macros removed
- former SOLVER package incorporated into "alberta_util",
"PLOT_ANSI" package removed
- ALBERTA_DEBUG=1 introduces additional safety checks
- changed "preserve_coarse_dofs" mechanism
- changed "fe_space" entry in DOF_[DOWB_]MATRIX into a
"row_fe_space" and a "col_fe_space". Fixed issue with
dof_compress() and different fe_spaces.
- added a "DOF_PTR_VEC" type.
