How to plot stress results on specific coordinates in Mechanical?
Hello, Is it possible to plot the stress values of my model at certain coordinates (theoretical weld transition) in Mechanical? The coordinates result from the joint lines of two plates and a defined evaluation distance to the joint lines. Thus, they usually do not lie exactly on a node, but can also lie in the middle of…
Are stresses extracted from DPF global or local to the element orientation
When using DPF to extract stresses are the values returned in the global system, or the local element system?
transform direction stresses to a different coordinate system node for node
for rotating the stress tensor I use the dpf.operators.geo.rotate function with an op.inputs.fields_container and an op.inputs.coordinate_system for an rotation field the problem is, the rotation is just performt for the first entry in the rotation field, not used as a field as I expected. Use case is getting stress in a…
DPF Install issue
I used the Ansys Python Manager to download python and relevant libraries. When I do that and then try to run dpf in with the following command from ansys.dpf import core as dpf in Jupyter notebook I get the following error. `---------------------------------------------------------------------------AttributeError…
DPF: time scoping in non-linear plastic structural analysis
I am new to the pyANSYS framework. Using ANSYS 2023 R2. I am running DPF in ANSYS Mechanical and post processing a structural non-linear plastic analysis with 200 substeps. I'm trying to scope my results in the time domain to the specific time that my max plasticity occurs. I do this with the following function and it kind…
How to get a safety factor result in a model with a custom yield limit for specific elements?
We want to get a safety factor result based on Von Mises stresses in a model where tensile yield strength must be based on elemental named selection.
Mechanical 2022R2 DPF VTK Export of Assembly & Plotting Parts.
Can we add something to the Mechanical DPF "VTK Export" operation so that it is easy to plot individual parts if wanted. For example if we were using PyVista.

How to create a result in DPF with deformed mesh whose scaling is different for each axis ?
Hello, As the title suggests, I want to create a result in DPF with deformed mesh whose scaling is different for each axis. When you normally create a result in ansys mechanical, you can adjust the scaling : But I want the scaling to be different for each axis, for example 1 in X, 3 in Y and 10 in Z. Does anyone know how…

DPF Operator C++
Hey everyone, I have a question about creating a custom operator in C++. Can this created operator be called in a DPF script in IronPython? Could someone please provide me with an example of creating such an operator and how to call it? Thank you in advance!
DPF operators like NSEL/ESEL
Does DPF have any operators that work like the NSEL APDL commands? Specifically I want to point to a CS in Mechanical and get all nodes within a certain radius to the cyl system axis (filter by its local X). I am looking for an efficient solution to work on large meshes with potentially thousands of these CSs.
DPF solution for force and moment reactions
Hi all. I am looking for a DPF solution in mechanical that is equal to a force and moment reaction probe. I would like to be able to scope to either geometry, a contact, or to a construction surface that cuts through geometry. I am more interested in auto export of the data than contours in Mechanical, so creation of a…
Example throws DPFServerException
Hi, I would like to use DPF for one of my tasks. I have installed ansys-dpf- core version 0.8.1and tried the example according to the documentation from ansys.dpf.core import Model from ansys.dpf.core import examples model = Model(examples.find_simple_bar()) print(model) But when I get to print line it raises this error:…
Error with DPF operator: stl_export
I am getting an error with stl export operator. Any ideas why?

How to move Element Table Data to Nodal in DPF
Element table data is per element, but often stored per node (i.e results at node I , J , K , L). How can use DPF to get this data as "Nodal" values. I suppose going the other way would work if it is easier, average the nodal values and get 1 value per element. What I am trying to do is create a plot of contact gap-volume.…
Get max stress values at the nodes instead of averaged
Hi, I am currently working on developing a Python script model in which an rst file will be read through dpf reader (dpf.Model(rst_file)) and get the nodal stress values. But, the problem here is that the nodal stress values should not be the averaged ones but the maximum among the element contributions. I mean let's say…
How to retrieve the material name of an element in mesh ?
I want to get the material name for each element so ican get it's properties in engineering data. i am using dpf but it only gave me the matid and i don't know how to link it to the name of the material. Thank you in advance. @AKD-Scripting-Team
How to merge workflow ?
Hello, I wrote a python result code to plot with dpf the total stiffness energy of named selection with name "R_" + number ("R_1", "R_2", "R_3", etc...). The user has to select his named selection in the property provider, and the plot appears as a result. My code is : def post_started(sender, analysis):# Do not edit this…
