SecondOrderSystem Class Referenceabstract

Detailed Description

Interface for SDIRK integrators.

Integration adapter for second-order dynamic systems of the form

\[ M a + C v + K u = F(t) \]

where the numerical stiffness of the differential equation is introduced by the linear left-hand terms (e.g. eig(K,M) span a wide range).
