Struct BoundaryConditions 

pub struct BoundaryConditions<'m, L> { /* private fields */ }

Degrees of freedom held fixed or at a value, chosen by node and component.

The components a layout has are the only ones that can be held, and an axis that a layout does not have is an error when compiling. The conditions borrow the sets they hold, such as those of the model they are for, so they cannot outlive them. Each is eliminated from the system unless it is made to be held by multipliers.

Implementations

impl<'m, L> BoundaryConditions<'m, L>

where L: Layout,

pub fn new() -> Self

pub fn fix<C, I>(self, component: C, nodes: &'m NodeSet) -> Self

where C: Component<L, I>,

Holds a component of every node in a set at its initial value.

pub fn fix_by<C, I>( self, enforcement: Enforcement, _: C, nodes: &'m NodeSet, ) -> Self

where C: Component<L, I>,

Holds a component of every node in a set at its initial value, the way given.

pub fn fix_nodes<C, I>( self, component: C, nodes: impl IntoIterator<Item = usize>, ) -> Self

where C: Component<L, I>,

Holds a component of the listed nodes at its initial value.

pub fn fix_nodes_by<C, I>( self, enforcement: Enforcement, _: C, nodes: impl IntoIterator<Item = usize>, ) -> Self

where C: Component<L, I>,

Holds a component of the listed nodes at its initial value, the way given.

pub fn fix_node<C, I>(self, component: C, node: usize) -> Self

where C: Component<L, I>,

Holds a component of a node at its initial value.

pub fn fix_node_by<C, I>( self, enforcement: Enforcement, _: C, node: usize, ) -> Self

where C: Component<L, I>,

Holds a component of a node at its initial value, the way given.

pub fn prescribe<C, I>( self, component: C, nodes: &'m NodeSet, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of every node in a set at a value.

pub fn prescribe_by<C, I>( self, enforcement: Enforcement, _: C, nodes: &'m NodeSet, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of every node in a set at a value, the way given.

pub fn prescribe_nodes<C, I>( self, component: C, nodes: impl IntoIterator<Item = usize>, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of the listed nodes at a value.

pub fn prescribe_nodes_by<C, I>( self, enforcement: Enforcement, _: C, nodes: impl IntoIterator<Item = usize>, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of the listed nodes at a value, the way given.

pub fn prescribe_node<C, I>( self, component: C, node: usize, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of a node at a value.

pub fn prescribe_node_by<C, I>( self, enforcement: Enforcement, _: C, node: usize, value: C::Value, ) -> Self

where C: Component<L, I> + Prescribable,

Holds a component of a node at a value, the way given.

pub fn conditions(&self) -> &[BoundaryCondition<'m>]

The conditions, in the order they were made.

pub fn constraint(&self) -> EqualityConstraints

The constraints holding the degrees of freedom, one for each condition.

A condition eliminated at its initial values is fixed, with the indices in ascending order and without repeats, and any other eliminated is prescribed. One held by multipliers has the indices as they are.
