fastmikeio 0.0.3

A faster version of DHI mikeio with some added functionalities

Installation

pip install fastmikeio

Notes

1. The package currently works only with 3D sigmal layer dfsu and vertical plane dfsu files

Features

1. Export the mesh directly from 3D Dfsu file using the code below:

import fastmikeio
dfsu = fastmikeio.read("3D dfsu.dfsu")
dfsu.geometry.to_mesh(output_fname)

2. Extract vertical profile from 3D dfsu file

x = [2000, 2100]
y = [100, 234]
output_filename = "Vertical Profile.dfsu"
vertical = dfsu.vertical_extractor(x, y, output_filename)

3. Retrive data as useful numpy array

print(dfsu)     # Helper statement to get item indices
print(dfsu.n_layers)
print(dfsu.n_timesteps)
dfsu.get_data(item_idx=1, time_idx=[0, dfsu.n_timesteps-1], layer_idx=2)    # (1, 2, 1, n_2d_elements)
dfsu.get_data(item_idx=1)       # (1, n_timesteps, n_layers, n_2d_elements)
dfsu.get_data(reshape=False)        # (n_items, n_timesteps, n_3d_elements)
dfsu.get_data()                     # (n_items, n_timesteps, n_layers, n_2d_elements)
