Transient calculation: Change discretization scheme

RodriguezFatz · August 8, 2012, 03:28

Dear all,

I would like to start each timestep with low order discretization schemes, then switch (after a few iterations) to higher ones in the same timestep for the last few iterations. This should be done automatically for a few thousand timesteps.
What am I supposed to do?

Thanks for any help!

Hi,

For any automation process, you can use journal files which contain TUI commands. In your case, you need a journal file generator which can be a simple program with any language. (refer to manual for more info about journal files)
