}

A model that cannot be analyzed as built, found by Domain::validate before any equation is assembled. Node and element indices are insertion order (the order the objects were added to the Domain), so a caller that created them from a table can map them straight back to a row.

Variants

LoadOnInactiveDof

A nodal load is applied to a DOF that no element stiffens, that is not fixed, that carries no mass and that no constraint uses: the load would have nothing to push against and would be silently dropped.

Fields

node: usize

dof: usize

DuplicateSlave

Two constraints define the same slave DOF.

Fields

node: usize

dof: usize

SlaveIsFixed

A constraint’s slave DOF is also fixed by the user.

Fields

node: usize

dof: usize

ConstraintCycle

A slave depends on itself, directly or through other slaves.

Fields

node: usize

dof: usize

ConstraintOnPrescribedDof

A constraint master is fixed with a nonzero value: constraints are homogeneous and have already eliminated its contribution, so its slaves would not follow it. (Prescribing such a DOF later is refused by Domain::can_prescribe for the same reason.)

Fields

node: usize

dof: usize

InconsistentInitialState

A slave’s nonzero initial displacement, velocity or acceleration disagrees with what its masters imply.

Fields

node: usize

dof: usize

MassOnConstrainedDof

Nodal mass on a slave that combines several unknowns, which a diagonal mass matrix cannot represent.

Fields

node: usize

dof: usize

IncompatibleElementLoad

An element load assigned to an element that cannot carry that kind of load (a body force on a beam, a beam load on a continuum element, an edge load past the element’s last edge).

Fields

element: usize

InvalidElement

An element rejected its own geometry or parameters.

Fields

element: usize

reason: &'static str
