Model Output as Boundary Condition for Nested Model

Hi there, I am relatively new to Delft and am using the Flexible Mesh Suite to develop a hydrodynamic and sediment transport model for a coastal system within a large bay area. My study site is a short piece of shoreline within the larger coastline and I am performing runs over long time periods, which becomes computationally challenging when incorporating the entire bay as part of my domain. Even when creating nested domains of finer scale within a coarser domain, the computational time is extreme. I am wondering if there is a way to easily use the output from a coarser, larger domain model run as the input for boundary conditions of a smaller, finer domain that is focused around my project site. I imagine this would be similar to an offline coupling of the Flow and Wave model, but I am looking to essentially couple two Flow models.

Any help would be much appreciated.

Thank you!

To add, I see that there is a NESTHD tool for Delft3D-FLOW but do not see this tool for the Flexible Mesh Suite. Thank you.

Hi Kevin, 
You can try to use Nesting toolbox in Delft DashBoard. I believe it supports D-Flow FM models.
