[petsc-users] TSSetExactFinalTime Behavior Without TSAdapt

[Paul Urbanczyk]

Hello,

I recently upgraded to the latest version of PETSc (3.7.1) from the git 
repository.

Running my code gave me an error message about TSSolve being in the 
wrong state and needing to call TSSetExactFinalTime.

I added this function call with TS_EXACTFINALTIME_STEPOVER, but when I 
re-ran my code, I got a seg fault and error messages pointing to 
TSAdaptChoose.

After fiddling around for a while, I found that I now needed to 
explicitly set the time step adaptation through TSAdaptSetType.

Can anyone confirm that this is so? If so, it might be helpful to note 
that in documentation or error messages somewhere.

Thanks,

Paul
