Dear @Ulrich,  
Yes, I did modify the OF adapter according to the suggestion of Moaxm.  
And I was able to run the dam break case with the Help of Kyle Davis.

Later on, it was a matter of fine-tuning the Implicit mapping. 😅

> After this we received a good agreement for the elastic dam break ([preCICE](https://www.dhcae-tools.com/preCICE.html)).

I actually started the work on this after looking at the LinkedIn postby DHCAE team. 😁

Edit: [Here](https://precice.discourse.group/t/iqn-fails-for-quickly-changing-forces-during-wetting-in-a-free-surface-fsi-problem/248/10) I have posted the results.
