Detailed Description

template<int TENS_DIM, int FUNC_DIM>
struct MoFEM::OpGetTensor1fromFunc< TENS_DIM, FUNC_DIM >

Get values from vector function at integration points and save them to MatrixDouble for Tensor1.

Template Parameters

TENS_DIM	Dimension of the stored output tensor in data_ptr.
FUNC_DIM	Dimension of the vector returned by vector_function.

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