CDTire/NVH

CDTire/NVH linearizes a CDTire/3D model instance around a stationary state — and this linearization includes the rotational effects if non-zero velocity is specified. The stationary state is to be specified by the user, and typically can be the result of a full vehicle non-linear transient simulation with CDTire/3D. The linearized state can be evaluated directly in predefined EVP (Eigenvalue problem) scenarios.
