Good morning PETSC team, I have been working on a code that uses the TSBDF object, and I have been able to run successful restarts with the BDF order 1.
However, due to the nonlinearity of the problem, restarting higher order methods from a single initial solution has led to trouble. Are there any built in functions or procedures to save the BDF solution vector with the necessary previous solutions so that it can be easily restarted? Maybe saving a set of binary files? Thank you, -Alfredo -- Alfredo Duarte Graduate Research Assistant The University of Texas at Austin
