The initialization part contains initialization records and an end_initia record

initialization
end_initia
The example below initializes a solid material
echo -yes
number_of_space_dimensions 2
materi_velocity
materi_strain_total
materi_stress
end_initia
The echo (always the first record), number_of_space_dimensions (always the second record), and end_initia record should be supplied always. Use echo -yes to echo the input and echo -no to not echo the input. Use number_of_space_dimensions 1 for 1D problems, etc.. The records materi_velocity, materi_strain_total and materi_stress create a velocity, strain and stress field in the entire domain. In the following sections, all possible initialization records are discussed. Most of these records create an unknown field, a physical field like a temperature field or or a strain field, over the computational domain.
