Hi, 

   Is there explicit support for second-order systems arising from structural 
dynamics in the TS library? 

   It can certainly be written as an equivalent first-order system, but some 
structural dynamics simulations prefer to tune the two-parameter Newmark 
solvers to provide extra damping for high-frequency modes. 

   Something equivalent might be possible for equivalent first-order 
representation, but I wanted to check if there is any support along those 
lines. 

Thanks,
Manav
