dofval#
Degrees-of-freedom
Shape [ndof]
xt::xtensor<double,1>
nodevec#
Nodal vectors
Shape [nnode, ndim]
xt::xtensor<double,2>
elemvec#
Nodal vectors stored per element
Allows treatment of all elements independently, no connectivity needed
Shape [nelem, nne, ndim]
xt::xtensor<double,3>
elemmat#
Matrices stored per element
Shape [nelem, nne*ndim, nne*ndim]
xt::xtensor<double,3>
qscalar#
Scalars stored per integration point
Shape [nelem, nip]
xt::xtensor<double,2>
qtensor (2nd order)#
2nd-order tensors stored per integration point
For certain elements, the number of dimensions of the tensor can be larger than the number of dimensions of the element (tdim >= ndim)
Shape [nelem, nip, tdim, tdim]
xt::xtensor<double,4>
qtensor (4th order)#
4th-order tensors stored per integration point
For certain elements, the number of dimensions of the tensor can be larger than the number of dimensions of the element (tdim >= ndim)
Shape [nelem, nip, tdim, tdim, tdim, tdim]
xt::xtensor<double,4>
