ANSYS DPF Introduction to POST API

This tutorial shows the first step to load the post module and to access some basic help.

Get started

from import examples
from ansys.dpf import post

Load a solution: this must be instantiated with the result filepath. Load a simple example file included with DPF-Post

simple_bar = examples.simple_bar
solution = post.load_solution(simple_bar)

Use the helpers

Solution information



Static solution object.

Locations information: the locations are used to defined where the result must be set.



Help on class locations in module ansys.dpf.core.common:

class locations(builtins.object)
 |  Contains locations str for scoping and field locations
 |  Attributes
 |  -----------
 |  none = "none"
 |  elemental = "Elemental"
 |      data is one per element
 |  elemental_nodal = "ElementalNodal"
 |      one per node per element
 |  nodal = "Nodal"
 |      one per node
 |  time_freq = "TimeFreq_sets"
 |      one per time set
 |  overall = "overall"
 |      applies everywhere
 |  time_freq_step = "TimeFreq_steps"
 |      one per time step
 |  Data descriptors defined here:
 |  __dict__
 |      dictionary for instance variables (if defined)
 |  __weakref__
 |      list of weak references to the object (if defined)
 |  ----------------------------------------------------------------------
 |  Data and other attributes defined here:
 |  elemental = 'Elemental'
 |  elemental_nodal = 'ElementalNodal'
 |  nodal = 'Nodal'
 |  none = 'none'
 |  overall = 'overall'
 |  time_freq = 'TimeFreq_sets'
 |  time_freq_step = 'TimeFreq_steps'
