Hi all, I am a new PETSc user (and new to MPI in general), and was wondering if someone could help me out with what I am sure is a basic question (if this is not the appropriate email list or there is a better place please let me know!).
Basically, I am writing a code that requires a solution to an ODE that will be used later on during runtime. I have written the basic ODE solver using TSRK, however I haven’t thought of a good way to store the actual solution at all time steps throughout the time evolution. I would like to avoid writing each time step to a file through the monitor function, and instead just plug each time step into an array. How is this usually done? I suppose the user defined struct that gets passed into the monitor function could contain a pointer to an array in main? This is how I would do this if the program wasn’t of the MPI variety, but I am not sure how to properly declare a pointer to an array declared as Vec and built through the usual PETSc process. Any tips are greatly appreciated!
