How do I Plot Stress Gradient on a Path Normal to the Selected Face at the Selected Node Using PyDPF?

Today’s Script Tip comes from Ayush Kumar, Senior Applications Engineer at Ansys.

Sometimes for a better engineering decision, it is important to analyze results along the normal to a face. This PyDPF example shows you how to plot a stress gradient normal at a selected node on a face.

# Import necessary modules: 
############################################################################### 
# First, import the DPF-Core module as ``dpf`` and import the 
# included examples file and ``DpfPlotter``
 
import matplotlib.pyplot as plt 
from ansys.dpf import core as dpf 
from ansys.dpf.core import operators as ops 
from ansys.dpf.core.plotter import DpfPlotter 
from ansys.dpf.core import examples 
############################################################################### 
# Next, link your result file(.rst) and print out the ``model`` object. The 
# :class:`Model <ansys.dpf.core.model.Model>` class helps to organize access 
# methods for the result by keeping track of the operators and data sources 
# used by the result file. 
path = r”\Path\to\file.rst” 
model = dpf.Model(path) 
print(model)

# Define the `node_id` normal to which a stress gradient should be plotted. 
node_id = 1928
