pyEMMP 0.0.2

A Python package developed to support EMMP tasks

Installation

pip install fastmikeio

Notes

1. The package currently works with the following dfsu formats:

• Dfsu 2D Horizontal
• Dfsu 3D Sigmal Layer
• Dfsu Vertical Plane

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 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)
