chrono::modal::ChModalDampingReductionR Class Reference
Description
Class for damping as reduction of the original damping matrix via the eigenvectors of the undamped assembly, i.e.
the same eigenvectors used for reducing M and K as M^ = Psi'*M*Psi etc, as: R^ = Psi'*R*Psi where Psi contains static and real-valued eigenmodes of the undamped assembly. Simple but not always good.

Constructor for the case where you want to pass an R matrix from an external source: R=Rcustom.
The Rcustom matrix must be of proper size, a square matrix of size (m_num_coords_vel_boundary + m_num_coords_vel_internal)
