Inversion test

This is an example for inversion calculation with small grid.

1. Run all cells of make_test_model.ipynb or python script make_test_mode.py for creating necessary input files:

   • source, receiver file (src_rec_test.dat)
   • true model (test_model_true.h5)
   • initial model (test_model_init.h5)

2. then run TOMOATT forward with input_params_pre.yml for calculating the true arrival times at the stations. The calculated travel time at the stations is saved in the file src_rec_test_out.dat
   Following command will run the forward simulation with the true model

mpirun --oversubscribe -n 8 ../../build/bin/TOMOATT -i input_params_pre.yml

Volumetric output data is saved in the file OUTPUT_FILES/out_data_sim_0.h5. This file may be visualized by paraview with opening the index file OUTPUT_FILES/out_data_sim_0.xmf.

3. run TOMOATT in inversion mode with input_params.yml, by the command

mpirun --oversubscribe -n 8 ../../build/bin/TOMOATT -i input_params.yml

The volumetric output data is again saved in the file OUTPUT_FILES/out_data_sim_0.h5.

4. The final output data is stored in OUTPUT_FILES/final_model.h5. This file may be visualized by e.g. check_3d_out.ipynb
