| - | Most of data are directly initialized with a default value that could be used by the code if these ones are not set a value specified by the user.\\ | ||
| - | Data could be used or not, this depends on the context. For this reason, useless data could be omitted in the data setup.\\ | ||
| - | The user must therefore ensure that every useful data are explicitly stated in the input3d.dat file unless he is sure that the default values are correct (if there is any doubt, you can check the file named " | ||
