TSRADAU5#
ODE solver using the external RADAU5 package, requires ./configure –download-radau5
Notes#
This uses its own nonlinear solver and dense matrix direct solver so PETSc SNES
and KSP
options do not apply.
Uses its own time-step adaptivity (but uses the TS rtol and atol, and initial timestep)
Uses its own memory for the dense matrix storage and factorization
Can only handle ODEs of the form \cdot{u} = -F(t,u) + G(t,u)
