Tutorial steps

1. Code

• Install and compile sem2dpack with seismogenic width option

2. Example

• Set the model parameters in the input file Par.inp
• If wanted, modify station coordinates in stations
• If wanted, modify model dimensions in layers

3. Results

• To visulaise the simulation outputs, you can use the PY library in py-example
• If necessary, modify the patth to simulation, in plot_fault_data
• Run the plot_fault_data to make plots of your choice.
