writer_session_t Derived Type

type, public, extends(../../../io_session_base_t) :: writer_session_t

PRIMARY TYPE FOR WRITING DATA - Use this for all file writing operations This is the only interface users should use for writing data. Provides type-safe writing operations with automatic backend selection.

Usage example: type(writer_session_t) :: writer_session call writer_session%open("output.bp", MPI_COMM_WORLD) call writer_session%write_data("timestep", current_step) call writer_session%write_data("pressure", p_field, start_dims, count_dims) call writer_session%close() call writer_session%write_attribute("ParaView", "vtk_xml_content") call writer_session%close()
