Nodal Translational Inertia

Computes the interial forces and mass proportional damping terms corresponding to nodal mass.

Description

This NodalKernel computes the component of translational inertial force proportional to nodal mass. Mass proportional Rayleigh damping is also computed by this NodalKernel. Please refer to C0TimoshenkoBeam for details.
