Perform 1D inversion

Given the three input files

• Parameter file in YAML format 3_input_params/input_params_1dinv_inv.yaml.
• Initial model file in HDF5 format 2_models/model_init_N61_61_61.h5.
• Traveltime data file in TEXT format OUTPUT_FILES/OUTPUT_FILES_1dinv_signal/src_rec_file_step_0000.dat.

users can perform inversion by

mpirun -n 8 TOMOATT -i 3_input_params/input_params_1dinv_inv.yaml

The results are output to the folder OUTPUT_FILES/OUTPUT_FILES_1dinv_inv.

• The updated model can be found as OUTPUT_FILES/OUTPUT_FILES_1dinv_inv/final_model.h5.

Some remarks about 1D model inversion

1. Applicability

1D inversion function only works when using a 1D initial model. This function solve a 2D eikonal equation to determine the traveltime with respect to depth and epicentral distance. The 1D model is build by extracting the first column of the input 3D model v(:,0,0). Thus, an unexpected results would be obtained if a 3D initial model was given.
