assembleNodeVector()

array_type::tensor< double, 2 > GooseFEM::Element::assembleNodeVector ( const array_type::tensor< size_t, 2 > &  conn, const array_type::tensor< double, 3 > &  elemvec  )

inline

Assemble nodal vector stored per element ("elemvec", shape [nelem, nne, ndim]) to nodal vector ("nodevec", shape [nnode, ndim]).

Parameters

conn	Connectivity.
elemvec	"elemvec".

Returns

"nodevec".

isDiagonal()

bool GooseFEM::Element::isDiagonal

(

const array_type::tensor< double, 3 > &

elemmat

)

Check that all of the matrices stored per elemmat (shape: [nelem, nne * ndim, nne * ndim]) are diagonal.

Parameters

elemmat

Element-vectors ("elemmat")

Returns

true if all element matrices are diagonal.
