pub fn new( objs_info: Vec<ObjectInfo>, engine: Option<Engine>, zero_dim: Vec<Box<dyn ZeroD>>, one_dim: Vec<Box<dyn OneD>>, connector: Vec<Box<dyn Conn>>, ) -> Result<System, String>

Source

pub fn advance<'a>(&'a mut self, dt: f64) -> &'a mut Self

Advance all objects in System by dt. The state of the objects is stored.

Source

pub fn advance_to_steady_state<'a>(&'a mut self) -> &'a mut Self

Advance all objects in System until steady state or until a max number of iterations/cycles is reached. All the stored data of objects are reseted

pub fn write_to_file( &self, file_name: &str, obj_name: &str, _range: Option<(usize, usize)>, )

Write the stored data from a object, obj_name, into a file file_name. If Engine has been added, only the data stored in the last cycle will be written as default. _range can be used to set the first and last index of the writable data.
