specfem::io::kernel_writer

template<typename OutputLibrary>
class kernel_writer : public specfem::io::writer

Writer for outputting sensitivity kernels to disk.

Template-based writer for adjoint sensitivity kernel data supporting multiple I/O backends. Kernels represent the gradient of a misfit function with respect to material properties.

Template Parameters:

OutputLibrary – Backend library type (HDF5, ASCII, NPY, NPZ, or ADIOS2)

Constructors

kernel_writer(const std::string &output_folder)

Construct a writer object.

Parameters:

  • assembly – SPECFEM++ assembly

  • output_folder – Path to output location (will be an .h5 file if using HDF5, and a folder if using ASCII)

virtual void write(specfem::assembly::assembly<specfem::dimension::type::dim2> &assembly) override

write the kernel data to disk

Parameters:

assembly – 2D Assembly object

inline virtual void write(specfem::assembly::assembly<specfem::dimension::type::dim3> &assembly) override

write the kernel data to disk

Parameters:

assembly – 3D Assembly object
