[petsc-users] [TimeStepping] Eventhandler

[Huck, Moritz]

I am using the fenics library for my PDE discretization.
I can not compile fenics with PETSc 3.10.3.
I will locate the exact error tomorrow.

What compatibility problem is this?  3.10.3 should be (binary and
source) backward compatible with other 3.10 releases, so if there is a
case where it is not, we need to understand it.


Regarding the event, it seems there are scenarios where something
important changes in the model and a conservative time step is
desirable, and other scenarios where the dynamics after the event are on
the same scale as before so it makes sense to continue with the same
step sizes.
