Without Stored Jacobian

template<bool UseSIMD>
struct jacobian_matrix<specfem::element::dimension_tag::dim2, false, UseSIMD> : public specfem::data_access::Accessor<specfem::datatype::AccessorType::point, specfem::data_access::DataClassType::jacobian_matrix, specfem::element::dimension_tag::dim2, UseSIMD>

Template specialization for 2D spectral elements without storing the Jacobian determinant.

Template Parameters:

UseSIMD – Boolean indicating whether to use SIMD

Subclassed by specfem::point::jacobian_matrix< specfem::element::dimension_tag::dim2, true, UseSIMD >

Typedefs

using simd = typename base_type::template simd<type_real>

SIMD data type.

Constructors

inline jacobian_matrix()
