Scaling spectral-line boundary (dfsu) with different scaling for each point along the boundary

[JeppeMathiasen]

I am at the moment trying to scale a spectral-line boundary (dfsu-format) for a SW model with different scaling for each point along the boundary. This is going to be used for a climate assessment study, to propagate the "future" waves, to help Port of Brisbane with their operability assessment.
I tried to use the mikeio.generic function to do the scaling, but it scales all points along the boundary with the same scaling. Furthermore, I need to do the scaling for each point differently for each month. The scaling of different months I could do by using the generic.extract and create each month as its individual .dfsu file and then return them all to one file with generic.concat. However, I still cannot scale the boundary points along the line differently.

Hope you guys can help me out!
Have a great day!

Cheers,
Jeppe

Hi @JeppeMathiasen , it sounds like a very relevant use case. Unfortunately, I don't see a way to achieve this with the current version of MIKE Core as it does not support writing dfsu-spectra files. But that could be made of course... The https://github.com/DHI/mikecore-python/blob/master/mikecore/DfsuBuilder.py needs to extended with the spectra information similar to the read part of https://github.com/DHI/mikecore-python/blob/master/mikecore/DfsuFile.py
