const Eigen::VectorXd &	vector (const FERequirement &feRequirements, VectorAffordance affordance, DBCOption dbcOption=DBCOption::Full)
	Calculates the vectorial quantity requested by the feRequirements and the affordance. Depending on the requested DBCOption, the raw, reduced or full vector is returned. Raw means the degrees of freedom associated with dirichlet boundary conditions are not changed. Full means that degrees of freedom associated with dirichlet boundary conditions are set to zero in the vector. Reduced means that degrees of freedom associated with dirichlet boundary conditions are removed and the returned vector has reduced size. More...

const Eigen::VectorXd &	vector (DBCOption dbcOption)
	Calculates the vectorial quantity requested by the bound feRequirements and the affordance. Depending on the requested DBCOption, the raw, reduced or full vector is returned.
