Non Uniform Roughness, Temperature and Heat Flux at Surface

[hgopalan]

Summary

This draft PR proposes a framework to include non-uniform roughness length, temperature and heat flux at the lower surface for handling spatially varying roughness length in large wind farms, spatial-temporal varying one-way roughness-based wave coupling, spatial-temporal varying temperature and sensible heat flux.

MOST is replaced with an explicit stratification based parametrization. Currently, the method does not work work terrains and will be updated in the future.

The data is read in an ascii format to avoid the netCDF dependency. Will create a separate preprocessing tool to convert netCDF data into the ascii format.

ToDo:

1. Add wave-roughness information
2. Add variable heat flux

Caution: It is assumed that the time-period of input dataset is greater than CFD run-time. This avoids the need for special one-sided interpolation at the end of the dataset.

Should we revive this one now that we got the other one out of the way? ;)

[hgopalan]

We may need to discuss internally on cleaning up the preprocessing to make it more general and what variables to support. This was meant to be a POC on how we may do it.
