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:…

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.…
Usage of DPF operator vtk to fields
Hi all, I am using pyDPF I am trying to get the data from a VTK file, and combine it with results of RST file. I found the operator "vtk_to_fields" unfofortinately I could not figure out how to use this operator. I have already looked at the example as well as the tests in github but did not find anything useful. could you…
dpf.FieldsContainer item access by label name
I've explored the capabilities of Data Processing Framework (DPF) in getting and processing data of Mechanical analysis for possible application in ACT-extension. dpf.FieldsContainer is the object that stores results data for particular entity and time scoping. Target entity is a 'Location', result set is 'time…
How can I plot deformed and undeformed mesh ( with result) together using PyDPF?
I would like to plot result having deformed mesh and undeformed mesh after getting results from PyDPF. The plot should looks something similar to Mechanical, like below.

How to plot result on cut mesh using PyDPF
Hi I would like to plot a one side of a volume geometry, for which I have nodal results, and would like to cut the geometry with specific plane. I have tried the mesh_plan_clip operator but as soon as I use it, the output mesh is cannot really plot the results. I have tried to create a possible solution with the PyVista…
How do I get the centroid of my contact elements
I want to save the centroid of the contact elements in all my contacts in a CSV. How would I do that in Mechanical?
How do i extract h5 results using DPF?
Hello Ansys developers: I'am trying to extract some results from an h5 file to plot them using Python Result, but i couldn't found how to read the h5 file and extract my fields. is it even possible ? Thank you in advance
[DPF] An unexpected error occurred - rst file used by another program
Hello, I'm writing some codes in DPF in a python result inside my modal analysis, so I need to read the rst file with the dataSource accessed with the "dpf.DataSources(analysis.ResultFileName)" command. My code works well, but when I want to resolve my modal analysis, it shows this error : An unexpected error occurred :…
How to plot within a Python result the total stiffness energy in a named selection with ansys dpf ?
Hello everyone, As the title suggest, I want to plot within a Python result the total stiffness energy in a named selection with ansys dpf. I made something that plot the stiffness energy by element on a given named selection, and I think I have to use fields operators to plot the total stiffness energy on the named…
How do i extract force reaction table from rst file using DPF Post?
Hello Ansys developers: recently i am trying to extract force reaction from rst file without opening Ansys Mechanical. As the below pic shows, i want to get the forces on the whole process time steps. Thus, i implemented such code to get my target values. But i get the following error msg: I suppose that i have defined a…
ANSYS Version used by PyMAPDL reader, pyDPF
Hello, DPF and possibly the PyMAPDL reader, use libraries or other files that come with an ANSYS installation. When a script that uses PyMAPDL or DPF is executing, I would like to know which ANSYS installation it is using (I have multiple ANSYS versions installed). How would I do that?

PyDPF - Remove midside nodes
Hi guys, Can I remove midside nodes from the extracted nodes, using Pydpf?
Identify elements that has atleast one face on the surface
Greetings! My objective is to retrieve elements that feature at least one surface face. To achieve this, I attempted using the following instructions: skinOp = dpf.operators.mesh.skin(mesh) skin_mesh = skinOp.outputs.mesh() However, the above commands yield surface elements that have been converted to 2D elements. The…
How to multiply all elements of a field
Dear all To get the total probability of survival (one scalar) I need to multiply the probality of survival of each element. This data I have in a dpf field. What would be the easiest way to this? Do I need to loop over the entries or is there some kind of vector operation? Regards Lorenz
Identifying element IDs with discrepancies in number of stress tensors and connected nodes
Dear Team, I am using dpf to read an .rst file and extract elementalNodal stresses. However, I have encountered an issue with some elements in the model. Specifically, when I try to obtain the stress tensor for certain elements, dpf outputs stresses at 8 nodes (model.results.stress.eval()[0].get_entity_data(x)), whereas…
Changing field mesh scoping
I have created a field in DPF and now I would like to limit to a subset of the mesh on which it was originally created without recomputing it. I have tried: ns_scope = dpf.mesh_scoping_factory.named_selection_scoping('BLADE_N', model) subset_op = dpf.operators.scoping.rescope() # operator instantiation…
Get elemental nodal stress array along with corresponding node ids
Dear Team, I am reaching out for help with organizing stress tensors for all elemental nodes using the API call (self.model.results.stress.eval()[0].data). This API call generates an array of stress tensors (elementalNodal) for all the elements, and I need to create another array with the corresponding node IDs for each…

PyDPF - Select Surface nodes
Hi guys, Is there an method to extract all the surface nodes from a rst file? For the moment, I create a new component on mechanical with all the surface nodes, and I extract it during the postprocess. But I cannot always modify the model on mechanical. Thanks, Tommaso
