Postprocessor

The postprocessor module provides methods to postprocess the results of a cardiac simulation. Use this module to extract and visualize results from simulation output files, such as LS-DYNA’s d3plot files and other relevant information.

This module includes two main classes:

• ansys.health.heart.post.dpf_utils.D3plotReader: This class provides methods to read LS-DYNA d3plot files.

• ansys.health.heart.post.dpf_utils.EPpostprocessor: This class provides methods to postprocess electrophysiology simulation results.

These classes build on PyDPF to make it easier to extract relevant simulation results. For example, you can use the ansys.health.heart.post.dpf_utils.EPpostprocessor class to extract the transmembrane potential and other quantities from simulation results.

Here is an example of how to use these classes:

from ansys.health.heart.post.dpf_utils import D3plotReader, EPpostprocessor

# Load a d3plot file
reader = D3plotReader("path-to-d3plot-file")

# Extract electrophysiology fields at step 10
ep_fields = reader.get_ep_fields(at_step=10)

# Extract displacement at 200 ms
displacement = reader.get_displacement(time=200)
