Méthodes protégées

Méthode Description
CalculateUnknownDisplacements ( ) : KeyedVector

Calculates part of the problem for unknown displacements
CalculateUnknownReactions ( KeyedVector unknownDisplacements ) : KeyedVector

Calculates part of the stiffness equations for the unknown reactions.
CombineExternalForcesOnReactionNodesWithReactions ( KeyedVector reactions ) : KeyedVector

The user may have placed reactions directly on to fixed supports. These are ignored during the calculation, but the correct answer for the total reaction must include them
CreateResults ( KeyedVector displacements, KeyedVector reactions ) : FiniteElementResults

Puts the data into the results data structure.
Solve ( StiffnessMatrix stiffnessMatrix, KeyedVector forceVector ) : KeyedVector

Solves AX=B for X.
ThrowIfNotAValidModel ( ) : void

Checks as to whether the model is valid for solving.
