Detailed Description

template<int TENS_DIM, int FUNC_DIM>
struct MoFEM::OpGetTensor2SymmetricfromFunc< TENS_DIM, FUNC_DIM >

Get values from matrix function in symmetric tensor storage at integration points and save them to MatrixDouble for symmetric Tensor2.

Template Parameters
TENS_DIMDimension of the stored output symmetric tensor in data_ptr.
FUNC_DIMDimension of the symmetric matrix returned by matrix_function.

If FUNC_DIM is larger than TENS_DIM, only the leading TENS_DIM by TENS_DIM symmetric block is copied to the output tensor. If TENS_DIM is larger than FUNC_DIM, doWork returns a data inconsistency error.

Examples
mofem/tutorials/vec-11_elastic_tie_mesh/elastic_tie_mesh.cpp.
