OpenDA and setting up DuD for many boundary nodes (.bc file)?

[PL6680]

Hello,

I am getting familiar with using OpenDA for model calibration. I am using Delft3D FM 2025.01.

I am trying to set up a DuD algorithm to calibrate tidal constituents of my model boundaries using a .bc file. From my understanding I need to specify in the "StochModel.xml" and "dflowfmModel.xml" all of the boundary nodes the algorithm will test. Does this mean in order to run the algorithm for a total of 27 bounday nodes and calibration to the M2 and S2 Amplitude and phases i must specify in the xml each boundary each node? Example below:

exchangeItems
vector id="EAST_BND_0001.waterlevelbnd amplitude.M2" ioObjectId="bcfile"/
vector id="EAST_BND_0001.waterlevelbnd phase.M2" ioObjectId="bcfile"/
vector id="EAST_BND_0001.waterlevelbnd amplitude.S2" ioObjectId="bcfile"/
vector id="EAST_BND_0001.waterlevelbnd phase.S2" ioObjectId="bcfile"/
vector id="EAST_BND_0002.waterlevelbnd amplitude.M2" ioObjectId="bcfile"/
vector id="EAST_BND_0002.waterlevelbnd phase.M2" ioObjectId="bcfile"/
vector id="EAST_BND_0002.waterlevelbnd amplitude.S2" ioObjectId="bcfile"/
vector id="EAST_BND_0002.waterlevelbnd phase.S2" ioObjectId="bcfile"/

Etc for each boundary node.

Any advice on how i should approach this is must appreciated as it seems this would be a rather long algorithm test if so.
Thanks

Hi PL6680 ;-)

I think the important question is do you want to let OpenDA calibrate all of them?
Do you expect (very) different values for the different nodes?
Do you have a large model that takes long to run?
Or maybe you also have a smaller simplified model as well?

Regards,
Erik

Hi @PL6680 is this still an open question or can we close this discussion?

Hello, apologies yes it can be closed. To summarise for any others reading, I ended up creating a coarser resolution domain that was able to be run very fast so i could test many DuD simulations. Ultimately adopting the best one and testing in my real model.

Great, thank you for your reply.
