Getting the `numlim.dt` file before the simulation finish

Is that possible to have the `numlim.dt` file before the simulation finish?

As we know that the `numlim.dt` file shows the numerical delimiter cell of the mesh during the simulation process.

We can fix and improve the mesh already when we know that the simulation going too slow.

Any idea, thought, and comment would be much appreciated. Thank you

If you are referring to the numerical timestep and limiting gridcells, have a look (in unstruc.exe) at: display --> Flownodes --> Timestep if jaautotimestep == 1. You will then see 'live' (instantaneously) what numerical timestep is required by each computational cell (in seconds), during the computation. I've added an example below (click to view full).



Does this help you?

Cheers,

Hi Freek,

Yes you are right. We can visually monitor the numerical timestep. It will help.

I just wondering if we can read the record too instead of only "live" monitoring the numerical timestep.

Anyhow, thank you very much.
