-
class external : public specfem::source_time_functions::stf¶
External source time function loaded from file.
Allows users to define custom source time functions by reading from external files in various formats (ASCII, HDF5, etc.).
Public Functions
-
external(const YAML::Node &external, const int nsteps, const type_real dt)¶
Construct an external source time function from YAML configuration.
- Parameters:
external – YAML node with file paths and format specification
nsteps – Number of time steps
dt – Time step size
-
virtual void compute_source_time_function(const type_real t0, const type_real dt, const int nsteps, Kokkos::View<type_real**, Kokkos::LayoutRight, Kokkos::HostSpace> source_time_function) override¶
Compute source time function values for all time steps.
- Parameters:
t0 – Start time
dt – Time step size
nsteps – Number of time steps
source_time_function – Output view to store computed values
-
inline virtual type_real get_tshift() const override¶
Get the time shift value.
- Returns:
Time shift value
-
virtual void update_tshift(type_real tshift) override¶
Throw error as time shift update is not supported.
-
virtual std::string print() const override¶
Get string representation of the source time function.
- Returns:
String describing the STF parameters
-
inline specfem::enums::seismogram_format get_format() const¶
Get the seismogram file format type.
- Returns:
specfem::enums::seismogram_format
-
inline virtual type_real get_t0() const override¶
Get the start time value.
- Returns:
Start time t0
-
inline std::string get_x_component() const¶
Get the file path for the X-component.
- Returns:
File path as a string
-
inline std::string get_y_component() const¶
Get the file path for the Y-component.
- Returns:
File path as a string
-
inline std::string get_z_component() const¶
Get the file path for the Z-component.
- Returns:
File path as a string
-
