Summary
This change lets simulations include both CMT sources and point-force sources at the same time. Previously the runtime enforced a single-source-type restriction. Two new tags are added to
Par_file. If they do not exist, both will default to.false.Changes
Par_filetag:USE_CMT_AND_FORCE_SOURCE. When set to.true., the solver reads bothCMTSOLUTIONandFORCESOLUTION. Default is.false.(backwards compatible).USE_BINARY_SOURCE_FILE(default.false.). The binary file encapsulates all source metadata, including external source-time functions (if used). When enabled, the arrayuser_source_time_function(:,:)stores only the STFs local to the current MPI slice, rather than the full global set. This is implemented by first locating sources within each MPI slice, then reading the corresponding source time functions. SeeEXAMPLES/application/cmt_force_hybrid/write_binary_source.f90for the reference writer and format details.USE_BINARY_SOURCE_FILE.Example
see
EXAMPLES/application/cmt_force_hybrid/, run from step 1 to step 4.Performance
USE_BINARY_SOURCE_FILEsignificantly reduces memory usage when thousands of events use distinct external source time functions (e.g., in simulations that rely on representation theorem).
