Setting up multiple forcing on boundary conditions
boundary conditions multiple forcing water level
Answer (Unmark)

According to D-Flow FM User Manual: “A support point can have multiple forcing quantities of the same type (i.e. water level, velocity, Riemann, Neumann or discharge). These quantities are added up. This can be relevant to add a surge level to an astronomical water level for example”.
However when setting up 2 forcing for water level (i.e. astronomical + time series, or 2 different time series), and inspecting results after run for a nearby observation point, it seems that D-FLOW does not add both series, instead it doubles the first value stored in “WaterLevel.bc” file.
Is this a software bug or am I doing something wrong?
I'm using Delft3D FM Suite 2017 HMWQ 1.2.2.36603
Kind regards,
Sebastian
