Hi

This would probably be some new DataArray of Int8 type in CellData. Any other ideas?

The VTU format definition may be found at

Hi

It would probably be easier to get the BC_ID's directly in ResultOutputSolver and dispatching it with the other variables. I will get a better look at this option tomorrow.

Hello there,

What if you use the VTK output? there the Boundaries are listed from material 100 on (or now from somethin higher?)

This only works for BC that you have given tho. This is the case if i got you right?

best regards

Hi, Peter:

though the problem posted by Basile is solved, modestly, I think that it would be nice to have the domain and boundary IDs saved as CellData also in the vtu files (just the same way as in the vtk file format), given that the vtk format does not fit parallel simulation results.

what do you think? is this posible?

Hi Cesar & others

There is now a 1st version of VTU output where the body & boundary indexes are saved. You need revision 5657 or never. Additionally you need to say in the Solver section of ResultOutputSolve

Code: Select all

Save Ids = Logical True
Any better proposals for keyword?

Hi,

Thank ou Peter, this will certainly be useful for quite some vtu users!

How about a more speaking keyword like

Code: Select all

Save Geometry Ids = Logical True
Matthias

P.S.: Wouldn't it be time for a new Windows binary when this is finalized...? ;)
Any news concerning the automated upload of the nightly builds?

Hi, Peter, Matthias:

Peter: thank you for the new feature and your quick response (as usual).

Concerning the keyword, I think

Code: Select all

Save Geometry Ids = Logical True
is a better choice.

As you wish "Save Geometry Ids" it is. Now in svn. -Peter
