PlotLinearSolverResult

This project is for plot LinearMSTMM solver result that is write with hdf5.

First import this package.

import PlotLinearSolverResult.read_from_hdf5 as rh
import matplotlib.pyplot as plt
import numpy as np

Then, initialize a H5File from h5 file path.

f = rh.H5File('test_write_vibration_characteristics.h5')

Using print_directory_information that can print the diractory information of the h5file to the dataset.

f.print_directory_information()

Get the keys of the attribute of the dataset.

keys = f.get_keys_attr_dset('/Animation/Index/Part_Beam/Part_BeamNodes')
keys[5]

​    'PhysicalDisplacementY'

Using get_index_attr_dset_in_data to get the index of the attribute of the dataset in the data over times.

Using get_keys_attr_dset_with_index_in_data to get the keys of the attribute of the dataset with the index in the data.

Using get_animation_data to get animation data over time.

Using get_TimesStamps to get TimesStamps data.

Finally, you can plot with times and data.

index = f.get_index_attr_dset_in_data('/Animation/Index/Part_Beam/Part_BeamNodes',keys[5])
animation_data = f.get_animation_data()
times = f.get_TimeStamps()
plt.plot(times,animation_data[:,index[0]])
