That is the problem I am trying to fix. Note, I am also adapting the time step when the solver converges but talks a lot of iterations. Thus, no need for recovery. It is the SNES failure, recover, cut time step, try again, that I am working in now. > > Did you read about -ts_error_if_step_fails on the man page Google, and found the command line args > for the > functional interface I just cited? > > Sorry, I missed this cite and used 'git grep' to see that it was there (Matt sent me the SNES version today so I knew what to look for). > >> but all the logic you're talking about is already in TS and > >> jury-rigging it on the outside is counterproductive.
