Input Parameters#
dm - DM to be used with TS
fun - function evaluation routine
ctx - context for residual evaluation
Calling sequence of fun#
t - time at step/stage being solved
U - state vector

U_tt - second time derivative of state vector
F - function vector
ctx - [optional] user-defined context for matrix evaluation routine (may be NULL)
