Input: initialization part

The initialization part contains initialization records and an end_initia record


initialization
...
initialization
end_initia

The example below initializes nearly incompressible Navier Stokes or a solid material


echo -yes
number_of_space_dimensions 2
materi_velocity
materi_stress
end_initia

The echo (always the first record), number_of_space_directions (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_directions 1 for 1D problems, etc.. The records materi_velocity and materi_stress create a velocity 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.
