|
|
//! @brief Data_Field has a set of data which stores field data by name.
|
||
|
|
//! It only stores field data's first address, i.e. a pointer to data's memory.
|
||
|
|
//! Users can update or obtain the data's pointer by its name.
|
||
|
|
//! Usually, users use Data_Field to store flow field data, such as rho, u, p, and so on.
