When mesh$degree == 2
, also g01
, g02
, and g12
.
fm_fem.fm_mesh_2d
: A list with elements c0

, va

ta
, and more if order > 1
. When aniso
is non-NULL, also g1aniso
matrices, etc.
fm_fem.fm_tensor
: A list with elements cc
, g1
, g2
.
fm_fem.fm_collect
: A list with elements c0
, c1
,
g1
, g2
, etc, and cc
(c0
for every model except fm_mesh_1d
with
degree=2
, for which it is c1
). If the base type for the collection
provides va
and ta
values, those are also returned.
fm_fem.fm_mesh_3d
: A list with elements c0
, c1
, g1
, g2
,
va
, ta
, and more if order > 2
.
