Modal rotation
We call the modal rotation matrix.Ψ

Integration of rotational parts In case of large deformation
A concept of local coordinate is employed

Modal analysis in local coordinate

Modal analysis in local coordinate The decoupled ODEs can be solved numerically
using semi-implicit integration:

Constraint Position constraint Orientation constraint

Position constraint Let λ be the number of constrained points
Forces do not have to be applied on the constrained points

Orientation constraint Similar to position constraint
